Tendon cell Tendon cell Tendon cells, or tenocytes, are elongated fibroblast type cells. The cytoplasm is stretched between the collagen fibres of the tendon. They have a central cell nucleus with a prominent nucleolus. Tendon cells have a well-developed rough endoplasmic reticulum and they are responsible for synthesis and turnover of tendon fibres and ground substance. Tendon cells form a connecting epithelial layer between the muscle and shell in molluscs. In gastropods, for example, the retractor muscles connect to the shell via tendon cells. Muscle cells are attached to the collagenous myo-tendon space via hemidesmosomes. The myo-tendon space is then attached to
Tendon transfer used to restore a single function. Transfer of one tendon to restore multiple functions will compromise strength and movement. These are examples of commonly performed tendon transfers. Many of the lower extremity tendon transfers were performed during the nineteenth century to improve ambulation in polio patients due to post-poliomyelitis paralysis. In the beginning o twentieth century, tendon transfers were used to correct congenital talipes equina. Tendon transfers were extensively performed during World Wars I and II to patients with upper extremity injuries. Tendon transfer A tendon transfer is a surgical process in which the insertion of a tendon is moved,
