what are the functions of tendons?
821768
A tendon (or sinew) is a tough band of fibrous connective tissue that connects muscle to bone, or muscle to muscle. They are similar to ligaments except that ligaments join one bone to another. Tendons are designed to withstand tension. Typically tendons connect muscles to bones; together, a combination of tendons and muscles can only exert a pulling force.\nComposition\n\nTendons are composed mainly of water, type-I collagen and cells called tenocytes. Minor fibrillar collagens, fibril-associated collagens and proteoglycans are present in small quantities and are critical for tendon structure. Most of the strength of tendon is due to the vertical, hierarchical arrangement of densely-packed collagen fibrils. Tenocytes are specialized fibroblasts responsible for the maintenance of collagen structure.\nAnatomy\n\nThe origin of a tendon is where it joins to a muscle. Collagen fibers from within the muscle organ are continuous with those of the tendon. A tendon inserts into bone at an enthesis where the collagen fibers are mineralised and integrated into bone tissue.\n\nTenocytes produce collagen molecules which aggregate end-to-end and side-to-side to produce collagen fibrils. Fibril bundles are organised by tenocytes to form fibres. Collagen fibres coalesce into macroaggregates. Groups of macroaggregates are bounded by connective tissue endotendon and are termed fascicles. Groups of fascicles are bounded by the epitendon and peritendon to form the tendon organ.\n\nBlood vessels may be visualised within the endotendon running parallel to collagen fibres, with occasional branching transverse anastomoses.\n\nThe internal tendon bulk is thought to contain no nerve fibres, however the epi- and peritendon contain nerve endings, while Golgi tendon organs are present at the junction between tendon and muscle.\n\nTendon length varies in all major groups and from monkey to person. Tendon length is practically the discerning factor where muscle size and potential muscle size is concerned. For example, a man with a 1 centimetre biceps tendon will have greater potential for muscle mass than a man with a longer tendon. Cases in point: Bodybuilders will generally have short tendons and are said to have 'great genetics', however not all bodybuilders are blessed with short tendons. Examples of people with short tendons (in particular the upper arms) are Casey Viator and Arnold Schwarzenegger. Tendon length is determined exclusively by genetics.\n\n[edit] Other information\n\nTendonitis refers to inflammation of a tendon.\n\nThe Achilles tendon is a particularly large tendon connecting the heel to the muscles of the calf. It is so named because the mythic hero Achilles was said to have been killed due to an injury at this spot.\n\nSinew was also widely used in the medieval times as a form of ancient elastic. Some specific uses include using sinew as thread for sewing, attaching feathers to arrows (see fletch), lashing tool blades to hafts, etc. It also recommended in survival guides as a material from which strong ropes can be made for items like traps or living structures.\n\nTendon (particularly beef tendon) is used as a food in some cuisines.

Could be biceps femoris, semitendinosis or semimembranosus. Which side is it on (inner or outer)? You can look at an online atlas of human anatomy to find out. One link is given below.\n\nBest treatment for tight, sore tendons: warmth (water bottle in a towel), gentle massage, exercise (starting with slow, gradual exercise, then gradually increasing it as the soreness decreases).

A tendon conects the muscle to bone, though some muscles are directly attached to bone without a tendon connecting them. Ligaments are a simular tissue, but connect one bone to another.\nMuscle spindles are a sensory fibre in muscles that are trigered by muscular contraction.

Because of the way their legs are built.\nThe tendons in bird's legs are arranged as a pulley-rope system so that the weight of the animal pulls on these tendons and keeps their fingers closed at rest. Thus they do not require voluntary muscle action to maintain their grasp on branches.\nThis is specially characteristic of songbirds. Others may rely on nests, platforms or other types of dwellings

Many, many functions:\n\nThe liver produces and excretes bile required for food digestion. \n\nThe liver performs several roles in carbohydrate metabolism: \nGluconeogenesis (the formation of glucose from certain amino acids, lactate or glycerol) \nGlycogenolysis (the formation of glucose from glycogen) \nGlycogenesis (the formation of glycogen from glucose) \nThe breakdown of insulin and other hormones \n\nThe liver is responsible for the mainstay of protein metabolism. \n\nThe liver also performs several roles in lipid metabolism: \nCholesterol synthesis \nThe production of triglycerides (fats). \nThe liver produces coagulation factors I (fibrinogen), II (prothrombin), V, VII, IX, and XI, as well as protein C, protein S and antithrombin. \n\nThe liver breaks down hemoglobin, creating metabolites that are added to bile as pigment. \n\nThe liver breaks down toxic substances and most medicinal products in a process called drug metabolism. This sometimes results in toxication, when the metabolite is more toxic than its precursor. \n\nThe liver converts ammonia to urea. \n\nThe liver stores a multitude of substances, including glucose in the form of glycogen, vitamin B12, iron, and copper.

Inside of your tendons you have stretch receptors.  Let's say you start climbing stairs.  Your breathing and heart rate will increase even though they are still getting sufficient oxygen.  This is because of information coming from your stretch receptors.  It is like a pre-emptive strike against insufficient oxygen supply.

Nice question, it has been asked before. \nI'll quote myself:\n"Because of the way their legs are built.\nThe tendons in bird's legs are arranged as a pulley-rope system so that the weight of the animal pulls on these tendons and keeps their fingers closed at rest. Thus they do not require voluntary muscle action to maintain their grasp on branches.\nThis is specially characteristic of songbirds.

Their function in the body. For instance, cells that require a lot of communication between them and the outside have a lot of transmembrane proteins that others that are more "isolated".

Since tendons have a decent blood supply, they'll take a while, but not too long, to recover. I'd say in about 4-6 more weeks you'll be completely recovered.\n\nThere's no risk of breaking the tendon by weight, but you could collapse against it and fall and break something else. Or, if during the surgery, they stitched it, by putting weight on it you could break the stitches. Just don't put weight on it.\n\nNo real vitamins help, but if you'd want real help on that, go see your doctor or a nutrition specialist. I don't think that vitamins will really help tendons though.\n\nWhatever happens, just remember to take the time recovering. Don't try to rush yourself. I did that when i broke my leg in 5 places at once, and since then, my leg hasn't been perfect.

"The liver is an astounding laboratory sustaining metabolism. Among its functions are purification of the blood, removing poisonous ammonia from proteins, detoxifying alcohol and drugs, controlling the body's sugar and cholesterol balance, making bile to digest fats, forming clotting factors for the blood and generating new blood cells. This myriad of functions makes clear why the liver is essential to life."

Its overall function is to collect information about the external conditions in relation to the body's internal state, to analyze this information, and to initiate appropriate responses to satisfy certain needs (Maintain Homeostasis). The most powerful of these needs is survival.
