Bicipital aponeurosis
Nerve that innervates the biceps muscle
Musclecutaneous
Joint in which the biceps muscle helps to prevent dislocation and stabilize the shoulder point
Glenohumeral joint
Function of the Glenohumeral joint of the biceps m.
Prevents dislocation and stabilize shoulder point
Join og the biceps m. that flex the elbow like lifting up heavy objects
Humero-ulnar joint
Function of the radioulnar joint of the biceps m.
Due to the orientation of the bicipital aponeurosis, helps the supinator muscle to supinate the forearm
