Peritenon

Peritenon is a term used in anatomy to describe a layer of tissue that surrounds a tendon. It is a type of connective tissue that provides nourishment and support to the tendon, allowing it to function properly.

Structure

The peritenon is composed of two layers: the outer epitenon and the inner endotenon. The epitendon is a thin, fibrous layer that provides a protective barrier for the tendon. The endotenon is a loose, areolar tissue that contains the blood vessels, nerves, and lymphatics that supply the tendon.

Function

The primary function of the peritenon is to provide a conduit for the blood vessels, nerves, and lymphatics that supply the tendon. This allows the tendon to receive the nutrients and oxygen it needs to function properly. The peritenon also plays a role in the repair and regeneration of tendons following injury.

Clinical significance

Injuries to the peritenon, such as peritendinitis, can cause pain and inflammation. This can result in reduced mobility and function of the affected tendon. Treatment typically involves rest, physical therapy, and in some cases, surgery.
