Connective Tissue Types and Examples

As the name implies, connective tissue serves a connecting function. It supports and binds other tissues in the body. Unlike epithelial tissue, which has cells that are closely packed together, connective tissue typically has cells scattered throughout an extracellular matrix of fibrous proteins and glycoproteins attached to a basement membrane. The primary elements of connective tissue include a ground substance, fibers, and cells. There are three main groups of connective tissues:Loose connective tissue holds organs in place and attaches epithelial tissue to other underlying tissues.Dense connective tissue helps attach muscles to bones and link bones together at joints.Specialized connective tissue encompasses a number of different tissues with specialized cells and unique ground substances. Some are solid and strong, while others are fluid and flexible. Examples include adipose, cartilage, bone, blood, and lymph. The ground substance acts as a fluid matrix that suspends the cells and fibers within the particular connective tissue type. Connective tissue fibers and matrix are synthesized by specialized cells called fibroblasts. There are three main groups of connective tissues: loose connective tissue, dense connective tissue, and specialized connective tissue. Loose Connective Tissue This image of loose connective tissue shows collagenous fibers (red), elastic fibers (black), matrix, and fibroblasts (cells that produce the fibers). Ed Reschke/Photolibrary/Getty Images In vertebrates, the most common type of connective tissue is loose connective tissue. It holds organs in place and attaches epithelial tissue to other underlying tissues. Loose connective tissue is named so because of the weave and type of its constituent fibers. These fibers form an irregular network with spaces between the fibers. The spaces are filled with ground substance. The three main types of loose connective fibers include collagenous, elastic, and reticular fibers. Collagenous fibers are made of collagen and consist of bundles of fibrils that are coils of collagen molecules. These fibers help to strengthen connective tissue.Elastic fibers  are made of the protein elastin and are stretchable.  They help to give connective tissue elasticity.Reticular fibers  join connective tissues to other tissues. Loose connective tissues provide support, flexibility, and strength required to support internal organs and structures such as blood vessels, lymph vessels, and nerves. Dense Connective Tissue This image of the dermis of the skin shows dense fibrous connective tissue. Irregular collagenous fibers (pink) and fibroblast nuclei (purple) can be seen. Ed Reschke/Photolibrary/Getty Images Another type of connective tissue is dense or fibrous connective tissue, which can be found in tendons and ligaments. These structures help attach muscles to bones and link bones together at joints. Dense connective tissue is composed of large amounts of closely packed collagenous fibers. In comparison to loose connective tissue, dense tissue has a higher proportion of collagenous fibers to ground substance. It is thicker and stronger than loose connective tissue and forms a protective capsule layer around organs such as the liver and kidneys. Dense connective tissue can be categorized into dense regular, dense irregular, and elastic connective tissues. Dense regular: Tendons and ligaments are examples of dense regular connective tissue.Dense irregular: Much of the dermis layer of the skin is composed of dense irregular connective tissue. The membrane capsule surrounding several organs is also dense irregular tissue.Elastic: These tissues enable stretching in structures such as arteries, vocal cords, the trachea, and bronchial tubes in the lungs. Specialized Connective Tissues This image shows a sample of fat tissue with fat cells (adipocytes, blue) surrounded by fine strands of supportive connective tissue. Adipose tissue forms an insulating layer under the skin, storing energy in the form of fat. Steve Gschmeissner/Science Photo Library/Getty Images Specialized connective tissues include a number of different tissues with specialized cells and unique ground substances. Some of these tissues are solid and strong, while others are fluid and flexible. Examples include adipose, cartilage, bone, blood, and lymph. Adipose Tissue Adipose tissue is a form of loose connective tissue that stores fat. Adipose lines organs and body cavities to protect organs and insulate the body against heat loss. Adipose tissue also produces endocrine hormones that influence activities such as blood clotting, insulin sensitivity, and fat storage. The primary cells of adipose are adipocytes. These cells store fat in the form of triglycerides. Adipocytes appear round and swollen when fat is being stored and shrink as fat is used. Most adipose tissue is described as white adipose which functions in the storage of energy. Both brown and beige adipose burn fat and produce heat. Cartilage This micrograph shows hyaline cartilage, a semi-rigid connective tissue from a human trachea (windpipe). Steve Gschmeissner/Science Photo Library/Getty Images Cartilage is a form of fibrous connective tissue that is composed of closely packed collagenous fibers in a rubbery gelatinous substance called chondrin. The skeletons of sharks and human embryos are composed of cartilage. Cartilage also provides flexible support for certain structures in adult humans including the nose, trachea, and ears. There are three different types of cartilage, each with different characteristics. Hyaline cartilage is the most common type and is found in areas such as the trachea, ribs, and nose. Hyaline cartilage is flexible, elastic, and surrounded by a dense membrane called perichondrium.Fibrocartilage is the strongest type of cartilage and composed of hyaline and dense collagen fibers. It is inflexible, tough, and located in areas such as between vertebrae, in some joints, and in heart valves. Fibrocartilage does not have perichondrium.Elastic cartilage contains elastic fibers and is the most flexible type of cartilage. It is found in locations such as the ear and larynx (voice box). Bone Tissue This micrograph shows cancellous (spongy) bone from a vertebra. Cancellous bone is characterized by a honeycomb arrangement, comprising a network of trabeculae (rod-shaped tissue). These structures provide support and strength to the bone. Susumu Nishinaga/Science Photo Library/Getty Images Bone is a type of mineralized connective tissue that contains collagen and calcium phosphate, a mineral crystal. Calcium phosphate gives bone its firmness. There are two types of bone tissue: spongy and compact. Spongy bone, also called cancellous bone, gets its name because of its spongy appearance. The large spaces, or vascular cavities, in this type of bone tissue contain blood vessels and bone marrow. Spongy bone is the first bone type formed during bone formation and is surrounded by compact bone.Compact bone, or cortical bone, is strong, dense, and forms the hard outer bone surface. Small canals within the tissue allow for the passage of blood vessels and nerves. Mature bone cells, or osteocytes, are found in compact bone. Blood and Lymph This is a micrograph of a group of red blood cells (erythrocytes) traveling through an arteriole (small branch of an artery). P.M. Motta S. Correr/Science Photo Library/Getty Images Interestingly enough, blood is considered to be a type of connective tissue. Like other connective tissue types, blood is derived from mesoderm, the middle germ layer of developing embryos. Blood also serves to connect other organ systems together by supplying them with nutrients and transporting signal molecules between cells. Plasma is the extracellular matrix of blood with red blood cells, white blood cells, and platelets suspended in the plasma. Lymph is another type of fluid connective tissue. This clear fluid originates from blood plasma that exits blood vessels at capillary beds. A component of the lymphatic system, lymph contains immune system cells that protect the body against pathogens. Lymph is delivered back to blood circulation via lymphatic vessels. Animal Tissue Types In addition to connective tissue, other tissue types of the body include: Epithelial Tissue: This tissue type covers body surfaces and lines body cavities providing protection and allowing for the absorption and secretion of substances.Muscle Tissue: Excitable cells capable of contraction allow muscle tissue to generate body movement.Nervous Tissue: This primary tissue of the nervous system allows for communication between various organs and tissues. It is composed of neurons and glial cells. Sources Animal Tissues - Bone. Atlas of Plant and Animal Histology.Animal Tissues - Cartilage. Atlas of Plant and Animal Histology.Stephens, Jacqueline M.

Daoism Free Essays

Beginnings and History The history of Daoism can befittingly be separated into four periods: Proto-Daoism, Classical Daoism, Modern Daoism and Contemporary Daoism. The first period, Proto-Daoism, spans the time from antiquity all the way to the 2nd century C. E. We will write a custom essay sample on Daoism or any similar topic only for you Order Now The intention behind this period being called â€Å"proto-Daoism† is that we have no information of any official Daoist religious organizations at this time. The classic works that were inscribed in the course of this period, the Daode jing and the Zhuangzi in particular, they were highly significant upon the flourishing of the classical Daoist tradition. Many textbooks on world religions still take this period as representing the essence of Daoism. This is simply an dull-witted and ambiguous interpretation of the m, entire history of Daoism. The second period, that of classical Daoist religion, starts in 142 C. E. when Zhang Daoling established the Way of the Celestial Masters, also known as the Way of Orthodox Unity, the first successful organized Daoist religious system. Daoist priests today claim to be ordained in a lineage that stretches back to this original founder. Two other important movements developed later during this period of classical Daoist religion: the Way of Highest Clarity (Shangqing Daoism) and the Way of Numinous Treasure (Lingbao Daoism). This period, between the 2nd and the 7th centuries can be called the classical period because scholars of Daoism look back to this time (known also as the medieval period of Chinese history) as the era in which many Daoist practices, texts and rituals initially took shape. Also during this period, Buddhism was brought to China by missionaries from India and Tibet. Buddhist ideas and practices were absorbed into Daoism (and vice-versa) but there were also periods of intense rivalry between Daoists and Buddhists. The classical period of Daoism ends with the Tang dynasty (618-906), one of the high-points of Chinese civilisation from the point of view of the development of art and culture. During the Tang dynasty Daoism became fully integrated with the imperial court system particularly under the reign of the Xuanzong Emperor (713-756). During this time Daoism functioned as the official religion of the imperial court and exerted complete supremacy over Buddhism. The period of modern Daoism begins with the Song Dynasty (960-1279), during which time the boundaries between elite Daoist religion, Buddhism, and local cults begin to be increasingly blurred. Based on the syncretism that began in this period, it becomes increasingly difficult to separate out Daoism as a religious category from the popular Chinese religious culture as it functions on the ground. In terms of elite Daoism, however, the most significant event was the founding of the Way of Complete Perfection (Quanzhen dao) by Wang Zhe (1113-1170). The Way of Complete Perfection is the major monastic form of Daoism that exists to this day alongside the more community-based priesthood of the celestial masters. The Way of Complete Perfection is devoted to the practice of internal alchemy, in which the energies of the body are refined through breathing and other forms of meditation into ever subtler forms, thus promoting longevity and even, in a few rare cases, the possibility of totally transcending the ordinary finitudes of human existence. The Way of Complete Perfection is also marked by its aim to â€Å"harmonise the three teachings† of Confucianism, Daoism and Buddhism, and became highly influential under the Mongol Yuan dynasty after Wang Zhe’s disciple Qiu Changchun (1148-1227) underook a three-year journey to the court of the Mongol warlord, Chinggis Khan. Despite the rhetoric of harmonization, further acrimonious debates with Buddhists developed at this time, and when the Daoists lost a series of these debates in1281 many Daoist texts were burned. Despite this setback, Daoism flourished during the subsequent Ming dynasty (1368-1644) and the year 1445 saw the compilation of the Daoist Canon (Daozang), a compendium of some 1,500 Daoist texts, under the patronage of the Yongle Emperor. In the Qing dynasty (1644-1911) Daoist ideas and practices became more entrenched in popular religious culture. Perhaps it would be more accurate to say that we have better historical evidence of the way popular religion functioned since many popular Daoist morality texts were published and the practice of Daoist-inspired arts such as Taiji quan (Tai Chi) and Qigong (Ch’i-kung) became increasingly widespread. The fourth period, since 1949, has been a near-total catastrophe for Daoism, particularly during the period of the Great Proletarian Cultural Revolution (1966-76) when many Daoist temples were destroyed and the overt functioning of the religion to all intents and purposes ceased to exist in mainland China. Since 1980 Daoism has begun to be practiced openly again in China and a new generation of Daoists are struggling to rebuild their temples and recover their tradition. On the other hand, through the emigration of many Chinese people across the world, Daoist temples have been established in Europe, the Americas and elsewhere and many popular Daoist practices such as Qigong and Taiji quan (Tai-chi) have taken root in the West. Until recently it was not certain that Daoism had survived this cataclysmic upheaval, but the study and practice of Daoism is beginning to flourish once again in China and throughout the world. Beliefs The primary belief is in learning and practicing â€Å"The Way† (Dao) which is the ultimate truth to the universe. The Dao has several meanings. It is the basis of all living things, it governs nature, and it is a method to live by. Daoists do not believe in extremes, instead focusing on the interdependence of things. There is no total good or evil or negative and positive. The Yin-Yang symbol exemplifies this view. The black represents the Yin the white represents the Yang. Yin is also associated with weakness and passivity and Yang with strength and activity. The symbol shows that within the Yang there exists the Yin and vice versa. All nature is the balance between the two. Daoist beliefs have undergone a series of changes in its history. In the 2nd Century the Shangqing school of Daoism emerged that focused on meditation, breathing and recitation of verses. This was the dominant practice of Daoism until about 1,100 AD. In the 5th Century AD, the Lingbao school emerged which borrowed much from Buddhist teachings such as reincarnation and cosmology. The use of talismans and the practice of alchemy were also associated with the Lingbao school. This school of thought was eventually absorbed into the Shangqing school during the Tang Dynasty. In the 6th Century, Zhengyi Daoists, who believed in protective talismans and rituals, emerged. Zhengyi Daoists performed offering rituals for showing thanks and the retreat ritual that includes repentance recitations and abstinence. This school of Daoism is still popular today. Around 1254, Daoist priest Wang Chongyang developed the Quanzhen school of Daoism. This school of thought used meditation and breathing to promote longevity, many are also vegetarian. The Quanzhen school also further combines the three main Chinese teachings of Confucianism, Daoism and Buddhism. Due to the influence of this school, by the late Song Dynasty (960-1279) many of the lines between Daoism and other religions were blurred. The Quanzhen school is also still prominent today. Another key component of Daoism is the De, which is the manifestation of the Dao in all things. De is defined as having virtue, morality and integrity. Historically, the highest achievement of a Daoist is to achieve immortality through breathing, meditation, helping others and the use of elixirs. In early Daoist practices, priests experimented with minerals to find an elixir for immortality, laying the groundwork for ancient Chinese chemistry. One of these inventions was gunpowder, which was discovered while searching for an elixir. Daoists believe that influential Daoists are transformed into immortals who help guide others. Tao, originally, meant ‘road’ and then implied ‘to rule’ and ‘principle’. Lao Zi used Tao to propound his ideological system; therefore his school of thinking is called Taoism. At the time Lao Zi created this religion, it was simply a school of philosophy. During the Eastern Han Dynasty, it became a religion. Tao is the origin of the eternal world. It is boundless in time and space. Ordinary people can become gods when they have Tao. This religion pursues immortality and preservation of health; its uttermost goal is to become an immortal being. This can be obtained through cultivating one’s moral character and perfecting one’s moral integrity. A Taoist phrase is to say an ordinary man can become immortal if he does good 3,000 times and accomplishes 800 exploits. Of course the number is symbolic. It requires people to do good without making it known to others as the gods will know it naturally, much like the Christian principle expressed in Matthew 6:3-4, â€Å"But when you give alms, do not let your left hand know what your right hand is doing, so that your alms may be done in secret; and your Father who sees in secret will reward you. † At certain dates, food may be set out as a sacrifice to the spirits of the deceased or the gods, such as during the Qingming Festival. This may include slaughtered animals, such as pigs and ducks, or fruit. Another form of sacrifice involves the burning of Joss paper, or Hell Bank Notes, on the assumption that images thus consumed by the fire will reappear—not as a mere image, but as the actual item—in the spirit world, making them available for revered ancestors and departed loved ones. At other points, a vegan diet or full fast may be observed. Also on particular holidays, street parades take place. These are lively affairs which invariably involve firecrackers and flower-covered floats broadcasting traditional music. They also variously include lion dances and dragon dances; human-occupied puppets (often of the â€Å"Seventh Lord† and â€Å"Eighth Lord†); tongji ( â€Å"spirit-medium; shaman†) who cut their skin with knives; Bajiajiang, which are Kungfu-practicing honor guards in demonic makeup; and palanquins carrying god-images. The various participants are not considered performers, but rather possessed by the gods and spirits in question. Fortune-telling—including astrology, I Ching, and other forms of divination—has long been considered a traditional Taoist pursuit. Mediumship is also widely encountered in some sects. There is an academic and social distinction between martial forms of mediumship (such as tongji) and the spirit-writing that is typically practiced through planchette writing Daoism Today The Taijitu (â€Å"yin and yang†) symbol as well as the Ba gua (â€Å"Eight Trigrams†) are connected with Daoist symbolism. While almost all Daoist societies make use of the yin and yang symbol, one could also call it Confucian, Neo-Confucian or pan-Chinese. The yin and yang make an â€Å"S† shape, with yin (Black or Red) on the right. One is likely to see this symbol as beautifications on Daoist organization flags and logos, temple floors, or stitched into clerical robes. In accordance Song Dynasty sources, it originated around the 10th century. Previously, yin and yang were symbolized by a tiger and dragon. A zigzag with seven stars is sometimes displayed, representing the Big Dipper (or the Bushel, the Chinese equivalent). In the Shang Dynasty the Big Dipper was considered a deity, while during the Han Dynasty, it was considered a qi path of the circumpolar god, Taiyi. Daoist temples in southern China and Taiwan may often be identified by their roofs, which feature Chinese dragons and phoenix made from multi-colored ceramic tiles. They also stand for the harmony of yin and yang (with the phoenix being yin). A related symbol is the flaming pearl which may be seen on such roofs between two dragons, as well as on the hairpin of a Celestial Master. In general though, Chinese Taoist architecture has no universal features that distinguish it from other structures. Daoist temples may fly square or triangular flags. They typically feature mystical writing or diagrams and are intended to fulfill various functions including providing guidance for the spirits of the dead, to bring good fortune, increase life span, etc. Other flags and banners may be those of the gods or immortals themselves. Today Taoism is mainly practiced in China and Taiwan. It has also spread to other parts of Asia and even around the world. There are about 20 million followers worldwide–most of them living in Taiwan. About 30,000 North Americans practice Taoism. The Chinese government has tried to suppress Taoism (severely at times in the past), but its teachings and practices still thrive and remain strong†¦ One thing that keeps Taoism popular is its flexibility–it almost isn’t a religion, but a philosophy. Most followers practice Taoism in conjunction with Confucianism, Buddhism, and other religions. Many Chinese practice a mix of Confucianism and Taoism. Evangelization to Daoism Daoist are very involved in their own historic culture much like most other religions, things have always been a certain way for them, so they are comfortable in dealing with the â€Å"Dao† and in saying what’s life is life. Which brings a hard pint top bring across when a Christian makes it their goal to show a Daoist that there is value to life, and things do not simply happen for no reason. Many Christians, including me before this class, have no connection with Daoism like they would with Islam or Buddhism. But with 30 million followers Daoism is making a name for itself in the religious world. Daoist are far opposites from extremist, believing that is simply no evil and no good. So with a start I think as a Christian you have to hear them out and understand their beliefs as to why there is no good or why there is no evil. Otherwise it will just come across as you attacking them and having no care for their soul, and just talking to prove wrong. Once you are comfortable with one another, it’s your turn! You begin to show the good things in the world, and explain how they came to be and how God had a hand in all of it. Now I know this won’t work for every single individual you come across, but any reasonable person will give you a shot and that is all our God needs! Bibligraphy Littlejohn, Ronnie.

Essay On Steroids Example For Students

Essay On Steroids In the past three decades, steroids has been becoming a seriousproblem more than ever in the athletic field. Steroids are anabolic drugto build growth hormones that include the androgens (male sex hormones)principally testosterone and estrogen and progestogens (female sexhormones). Steroids were first developed for medical purposes. Theyre usedin controlling inflammation, strengthening weakened hearts, preventingconception, and alleviating symptoms of arthritis and asthma. Unfortunatelyresearch has shown that steroids have been abused in almost every kind ofsport. Although steroids contribute to a muscular body, usage should remainillegal because they physically deteriorate and mentally destroy the body. Many people are fascinated about steroids because of their ability tobuild up the body. Whether taken by injection or the pill it increasesstrength and endurance. Steroids also help in the healing process ofmuscular tissue by first injuring them, then the muscles heal quickeradding more fiber increasing their bulk. Many athletes turn to steroidsmore often because theyre cheaper then marijuana or cocaine. A ten weekcycle of testosterone cypinate and methandrostone costs only about onehundred dollars. Steroids are also very hard to trace because of theirwater base composition. They can pass through the body within two days. Allthese benefits of steroids help an athletes become more competitive andincrease their chance of being a winner. Of course everybody wants betterbiceps and triceps but when using steroids to achieve this goal there is alarge price to pay. However, steroids should remain illegal because they physicallydeteriorate the whole body system. When injected one risks the chances ofdeveloping hematoma and contracting AIDS. In women steroids contribute tothe growth of facial hair, enlargements of the clitoris, shrinkage of theuterus, sterility, deepening of the voice, decrease in breast size andirregularity of the menstrual cycle. In men steroids cause shrinkage of thetesticles, decrease in sperm count, sterility, impotence, prostateenlargement and growth of female breast. In both men and women hair loss,liver ailments, acne, atherosierosis and cancer are very common. Thisdangerous drug shortens the life span up to twenty years and increases thechance of obtaining diabetes, cardiovascular diseases and hypertension. Theside effects and reactions from enduring anabolic steroids are endless. Along with the physical problems there are also mental 54reactionsassociated with the usage of steroids. This drug becomes very addictive anddamaging to the mind. It causes violent episodes which an athlete can claima legal insanity defense to it. They get so wrapped up psychologically thatthe negative effects doesnt matter to them. Research has also discoveredthat steroids cause psychotic side effects sometimes referred to as roidmania. Along with these are wild aggressive, combative behavior,depression, listlessness and delusions during and after performance. Eventhough the game is over athletes want to continue competing. Steroidsmentally destroy the brain and ability to reason. Overall the usage of steroids is very damaging to the human body. Eventhough it physically builds up the body for better performance the risks ofuse are enormous. Steroids physically deteriorate and mentally destroy thebody. The usage of steroids provides an unfair advantage to non-userathletes and therefore should remain illegal for non-medical use.
