tendon

tendon,

tough cord composed of closely packed white fibers of connective tissue that serves to attach muscles to internal structures such as bones or other muscles. Sometimes when the muscle involved is thin and wide, the tendon is not a cord but a thin sheet known as an aponeurosis. The purpose of the tendon in attaching muscle to bone is to enable the power of the muscle to transfer over a distance. For example, when one wants to move a finger, specific muscles in the forearm contract and pull on ligaments that in turn pull the finger bones to produce the desired action.

Tendon

A cord connecting a muscle to another structure, often a bone. A tendon is a passive material, lengthening when the tension increases and shortening when it decreases. This characteristic contrasts with the active behavior of muscle. Away from its muscle, a tendon is a compact cord. At the muscle, it spreads into thin sheets called aponeuroses, which lie over and sometimes within the muscle belly. The large surface area of the aponeuroses allows the attachment of muscle fibers with a total cross-sectional area that is typically 50 times that of the tendon. See Muscle

Tendons are living tissues that contain cells. In adult tendons, the cells occupy only a very small proportion of the volume and have a negligible effect on the mechanical properties. Like other connective tissues, tendon depends on the protein collagen for its strength and rigidity. The arrangement of the long, thin collagenous fibers is essentially longitudinal, but incorporates a characteristic waviness known as crimp. The fibers lie within a matrix of aqueous gel. Thus, tendon is a fiber-reinforced composite (like fiberglass), but its collagen is much less stiff than the glass and its matrix is very much less stiff than the resin. See Collagen

The function of tendons is to transmit force. They allow the force from the muscle to be applied in a restricted region. For example, the main muscles of the fingers are in the forearm, with tendons to the fingertips. If the hand had to accommodate these muscles, it would be too plump to be functional. Tendon extension can also be significant in the movement of a joint. For example, the tendon which flexes a human thumb joint is about 7 in. (170 mm) long. The maximum force from its muscle stretches this tendon about 0.1 in. (2.9 mm), which corresponds to rotation of the joint through an angle of about 21^°. See Joint (anatomy)

Some tendons save energy by acting as springs. In humans, the Achilles tendon reduces the energy needed for running by about 35%. This tendon is stretched during the first half of each step, storing energy which is then returned during takeoff. This elastic energy transfer involves little energy loss, whereas the equivalent work done by muscles would require metabolic energy in both stages. See Connective tissue, Muscular system

Tendon

a cord consisting of connective tissue; a tendon attaches a muscle to a bone and causes a contracting muscle to move. Tendons are composed of thick, strong, inelastic collagen fibers. The fibers are continuous with the muscle fibers at one end and are interwoven into the periosteum at the other end. Tendons vary in shape; those attached to long muscles are cylindrical, and those attached to transverse muscles are flattened and are termed aponeuroses. The centrum tendineum and galea aponeurotica are distinctive in shape. Some tendons, for example, those of the long flexor muscles of the fingers and toes, are surrounded by a synovial membrane that releases a fluid enabling the tendons to slide easily during motion.

Tendon function may be impaired by inflammation or injury. Diseases of the tendons and synovial bursae are treated conservatively. Surgery is indicated when tendons are ruptured as a result of injury.

tendon

[′ten·dən] (anatomy) A white, glistening, fibrous cord which joins a muscle to some movable structure such as a bone or cartilage; tendons permit concentration of muscle force into a small area and allow the muscle to act at a distance. (civil engineering) A steel bar or wire that is tensioned, anchored to formed concrete, and allowed to regain its initial length to induce compressive stress in the concrete before use.

tendon

In prestressed concrete, a steel element such as a wire, cable, bar, rod, or strand used to impart prestress to the concrete when the element is placed under tension.

tendon

[ten´don] a cord or band of strong white fibrous tissue that connects a muscle to a bone. When the muscle contracts it pulls on the tendon, which moves the bone. Tendons are extremely tough and are seldom torn, even when an injury is severe enough to break a bone or tear a muscle. One of the most prominent tendons is the achilles tendon.

Frequently injured tendons. From Copstead, 1995.

ten·don

(ten'dŏn), [TA] A nondistensible fibrous cord or band of variable length that is the part of the muscle (some authorities, however, consider it as part of the muscle complex), which connects the fleshy (contractile) part of muscle with its bony attachment or other structure; it may unite with the fleshy part of the muscle at its extremity or may run along the side or in the center of the fleshy part for a longer or shorter distance, receiving the muscular fibers along its border; when determining the length of a muscle, the tendon length is included as well as the fleshy part; it consists of fascicles of densely arranged, almost parallel collagenous fibers, rows of elongated fibrocytes, and a minimum of ground substance. Synonym(s): tendo [TA], sinew [L. tendo]

tendon

A strong band of COLLAGEN fibres that joins muscle to bone or cartilage and transmits the force of muscle contraction to cause movement. Tendons are often provided with sheaths in which they move smoothly, lubricated by a fluid secreted by the sheath lining. Tendons may become inflamed, or may be torn or cut.

tendon

a bunch of parallel COLLAGEN fibres making up a band of CONNECTIVE TISSUE which serves to attach a muscle to a bone. The fibres become continuous with the collagen sheath around the muscle fibres and with the connective tissue covering the bone surface, making a strong cord with no weak connections.
