Document Summary

Muscles fascial compartments group muscles that have similar origin and function. Coracobrachialis and brachialis origin: coracoid process of scapula insertion: medial humerus actions: adducts humerus, flexes arm. Biceps brachii short head origin: corocoid process of scapula long head origin: supraglenoid tubercle insertion: greater tubercle of humerus actions: flexes elbow, supinates proximal radioulnar joint. Triceps brachii long head origin: infraglenoid tubercle lateral head origin: posterior shaft of humerus. Medial head: posterior shaft of humerus insertion: olecranon process action: extends the elbow. Anconeus origin: lateral epicondyle of humerus insertion: lateral surface olecranon process extends forearm, pronation/supination elbow. Anterior antebrachial compartment innervated by medial or ulnar nerve. Quadriceps femoris origin: rectus femoris and vastus muscles insertion: tibial tuberosity actions: knee extension, hip flexion. Hamstrings origin: tuberosity of ischium, linea aspera insertion: tibia, fibula actions: knee flexion, hip extension. Adductors origin: pubis insertion: femur and tibia actions: adduction of hip. Gracilis origin: ischiopubic ramus insertion: tibia actions: flexes, rotates medially, and adducts hip.
