Tendon cell

Tendon cell or tenocyte is a type of cell that is found in tendons, which are fibrous connective tissues that connect muscle to bone. The primary function of tendon cells is to maintain the structure and health of the tendon tissue.

Etymology

The term "tendon cell" is derived from the Greek words "tenon" meaning tendon and "kytos" meaning cell. The term "tenocyte" is a combination of "tenon" and "cyte", the latter of which is a common suffix in biology that refers to cells.

Structure and Function

Tendon cells are elongated, spindle-shaped cells that are aligned in parallel to the collagen fibers in the tendon. They have a central nucleus and a cytoplasm filled with rough endoplasmic reticulum, which is involved in protein synthesis. The primary function of tendon cells is to produce and maintain the extracellular matrix of the tendon, which consists mainly of collagen fibers. They also play a role in tendon repair and healing.
