Subtendinous Bursa of Triceps Brachii Muscle (Right)

Structure

The subtendinous bursa of triceps brachii muscle is a closed sac of synovial fluid which sits deep to the tendinous insertion of the triceps brachii muscle (Standring, 2016).

Function

The subtendinous bursa of triceps brachii muscle permits friction-free movement between the tendon of the triceps brachii and the olecranon process of the ulna (Standring, 2016). Inflammation due to pressure, friction, or infection can cause the elbow to swell and limit elbow movement (Standring, 2016).
