tendons and ligaments are composed primarily of?

Mostly, the protein called collagen.  Some elastin, too, but not a lot.\n\nCartilege is actually the stuff that "pads" the joints, and makes up the middle bit of your nose after the bone stops, and makes up your fingernails and toenails...  Not really a component of tendons and ligaments.\n\nChemically, tendons and ligaments are essentially identical; the difference is that a tendon connects bone and muscle; a ligament, muscle and muscle

To the above mention person, idiot this is english if you are not versed in scientific terms don't go spouting nonsense. Cartilages are not true bone material, they are soft tissue like what our noses and most non skeletal fishes such as sharks and rays are composed of. But a toad has a skeletal structure and the cartilages are the same as a humans, found at the bridge of the nose area.

Synovial joints have a dense fibrous capsule which may be reinforced by ligaments and muscles.\n\nSynovial fluid is a thick, stringy fluid found in the cavities of synovial joints. With its egg-like consistency (synovial comes from Latin for "egg"), synovial fluid reduces friction between the articular cartilage and other tissues in joints to lubricate and cushion them during movement.

Elements:\n\nMain constituents are H, C, O, N, with considerable amounts of Ca, Na, P, S, Cl, less Mg, K, Fe, I, and traces of about any common element.\n\nThe most common simple molecule is water.\n\nMost important "inorganic" compounds are CaCO3 (in the bones), NaCl (dissolved in the water) and Ca2(PO4)OH in the teeth.\n\nThe main classes of chemicals are carbohydrates and proteins, which form the main structural elements of our cells as well as most of the functional framework. (DNA for instance has a modified carbohydrate linked by phosphate as its structural basis). Fats (triglycerides of fatty acids) are abundant, but don't participate structurally in most features of human anatomy except as fillers (lower skin, lips, breasts...)

Acetic acid is in about a 4-5% concentration in vinegar. It dissolves out the calcium in the bone, leaving the collagen and thus making it soft.

I agree with Kanajlo's answer as being correct, and will check it also as  best answer. "Oblique Popliteal Ligament\nOr you could say popliteus or popliteum"

Mesoderm: One of the three primary germ cell layers -- the other two are the ectoderm and endoderm -- in the very early embryo. The mesoderm is the middle layer. It differentiates to gives rise to a number of tissues and structures including bone, muscle, connective tissue, and the middle layer of the skin. Some cells in mesodermal tissues retain the capacity to differentiate in diverse directions. For example, some cells in the bone marrow (mesoderm) can become liver (endoderm).

READ THIS NOW!\ni have always known this one!   : )  \n\nBones- ( as in the human skeleton) is mainly made of a protein called - Collagen(this is the actual word for this protein used in most of our body)!!. bones also contain bone marrow in the centre(this is needed) calcium phosphate and other mineral compounds are then needed to strenghten and further form human bones. you can read the article in the link below to understand this more.\n\ni feel clever compared to the answers above me (jus kidding) . LOL!  : )  please give me 10 points cuz its for your homework   : )\n\n\nread this for your homework answer-( but do not plagiarise ) \nFramework of bones that supports and gives form to the body, protects its internal organs, and provides anchorage points for its muscles. It is composed of about 206 bones. Each bone and cartilage is made of a mineral, calcium phosphate, and protein (collagen). Bones of the skeleton are joined to each other by ligaments. In the human body, walking, running, arm and leg movements, hand actions, and even just standing, are all achieved by the operation of muscles attached to bones of the skeleton. Movement of the body is brought about by the move- able joints of the body. The elbow joint is a good example. Muscles are attached to bones by tendons, and contractions of the muscle bring about movement.

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.

Car·ti·lage    \n \nA tough, elastic, fibrous connective tissue found in various parts of the body, such as the joints, outer ear, and larynx. A major constituent of the embryonic and young vertebrate skeleton, it is converted largely to bone with maturation.\n\nBone    \n\nThe dense, semirigid, porous, calcified connective tissue forming the major portion of the skeleton of most vertebrates. It consists of a dense organic matrix and an inorganic, mineral component. \n\nThe definitions do not make it entirely clear, but basics first! \n\nCartilage is flexible connective tissue, bone is rigid, inflexible, and calcified. Try bending your upper ear, easy right? That's cartilage. Bone is not flexible (Like your skull.)  \n\nYour question was cut off, did you want to know the difference between a shark skeleton and a human's? A shark skeleton is almost entirely cartilage, a man's is mostly bone, with some connective cartilage.

those two are proteins and nucleic acids (DNA and RNA).  those two are present in all the living beings (the only problem with them is, that in viruses they are present - but some scientists belive that viruses are not living materia).\n\nthere are other organic components in living materia, such as lipids, carbohzdrates, vitamins, ferments etc.\n\nand those organic moleculas are composed of minerals - those which are listed in the first answer.
