A tendon is made of dense regular connective tissue, whose main cellular components are special fibroblasts called tendon cells (tenocytes). [3] Tendon cells synthesize the tendon's extracellular matrix, which abounds with densely-packed collagen fibers. The collagen fibers run parallel to each other and are grouped into fascicles.
A tendon connects muscle to bone, while a ligament connects bone to bone. [1] Injuries are common to this tendon, with tears, either partial or complete, being the most common. If the quadriceps tendon is completely torn, surgery will be required to regain function of the knee. [2] Without the quadriceps tendon, the knee cannot extend.
The tendon organ is a stretch receptor that signals the force developed by the muscle. The sensory endings of the Ib afferent are entwined amongst the musculotendinous strands of 10-20 extrafusal muscle fibers. [A] [3] See an animated version. When the muscle generates force, the sensory terminals are compressed.
A tendon is a tough, flexible band of fibrous connective tissue that connects muscles to bones. [12] The extra-cellular connective tissue between muscle fibers binds to tendons at the distal and proximal ends, and the tendon binds to the periosteum of individual bones at the muscle's origin and insertion. As muscles contract, tendons transmit ...
A tendon sheath is a layer of synovial membrane around a tendon. [1] It permits the tendon to stretch [2] and not adhere to the surrounding fascia. It contains a lubricating fluid (synovial fluid) that allows for smooth motions of the tendon during muscle contraction and joint movements. [3] It has two layers: synovial sheath; fibrous tendon sheath
In the horse, the biceps' function is to extend the shoulder and flex the elbow. It is composed of two short-fibred heads separated longitudinally by a thick internal tendon which stretches from the origin on the supraglenoid tubercle to the insertion on the medial radial tuberosity.
The Golgi tendon reflex, which is a reflex to extensive tension on a tendon; it functions to protect musculoskeletal integrity. The sensory receptors for this reflex are anatomically located deep in the tendon, while the sensory receptors for the MSR are inside the muscle.
The tendon of extensor carpi radialis brevis is usually the most major tendon to which the other tendons merge. [2] Function The common extensor tendon is the major ...
