Sinew

A sinew is a type of tendon, which is a tough band of fibrous connective tissue that usually connects muscle to bone and is capable of withstanding tension. Sinews are essential components of the musculoskeletal system, playing a crucial role in movement and stability of the body.

Structure

Sinews are composed primarily of collagen fibers, which provide them with their strength and flexibility. The collagen fibers are organized in parallel bundles, allowing the sinew to handle high tensile forces. The epitenon is a fine connective tissue sheath that surrounds the tendon, providing it with a smooth surface and facilitating movement.

Function

The primary function of sinews is to transmit the force generated by muscle contraction to the bones, thereby enabling movement. They also help maintain the posture of the body by stabilizing joints and supporting the skeleton.

Clinical significance

Sinews can be subject to various injuries and conditions, such as tendinitis, which is the inflammation of the tendon, and tendon rupture, which is a complete tear of the tendon fibers. These conditions can result from overuse, trauma, or degenerative changes.
