What is Serratus Anterior
deep elbow flexor that inserts onto the ulna.
What is the Brachialis
muscle in the elbow region responsible for rotating the forearm into a "palm down" position
What is the Supinator
What movement occurs at the wrist when the flexor carpi radialis and extensor carpi radialis longus muscles contract simultaneously?
What is Radial deviation
This nerve innervates the flexor carpi ulnaris
What is the Ulnar Nerve
muscle that acts upon the neck and shoulders and is often divided into 3 functional parts
What is Trapezius
Performs flexion of the elbow and supination of the forearm and also contributes to flexion at the glenohumeral joint.

The action of the anconeus muscle
What is extension of the elbow.
Which extensor muscle of the wrist also acts to extend the fingers of the hand?
What is Extensor Digitorum Longus
The muscles of the posterior forearm are usually innervated by this nerve
What is the Radial Nerve
rotator cuff muscle that is responsible for abduction and general glenohumeral stability.
What is Supraspinatus
This muscle inserts onto the lesser tubercle of the humerus and performs internal rotation of the GH jt.
What is the Subscapularis
This muscle assists the deltoid in shoulder extension as well as making elbow extension possible.
