muscle has a rib origin of ribs one through nine.
What is Serratus Anterior
The distal 1/2 of the anterior shaft of the humerus to the ulnar tuberosity are the attachments for this muscle.
What is the Brachialis
The lateral epicondyle of the humerus and the proximal ulna to the proximal 1/3 of the radius are the attachments of this muscle.
What is the Supinator
Flexor carpi radialis, extensor carpi radialis longus, and extensor carpi radialis brevis all have this action at the wrist joint
What is Radial Ddeviation
This nerve innervates the flexor carpi ulnaris
What is the Ulnar Nerve
is a muscle that is most often divided into 3 functional parts
What is Trapezius
Flexion of the shoulder at the glenohumeral joint, flexion of the elbow at the humeroular joint and supination of the forearm at the radioulnar joints are the action of this muscle.
The action of the anconeus muscle
What is extension of the elbow.

What is Extensor Carpi Radialis Brevis
The muscles of the posterior forearm are usually innervated by this nerve
What is the Radial Nerve
muscle attaches from the first rib to the clavicle.
What is Subclavius
This muscle attaches onto the lesser tubercle of the humerus
What is the Subscapularis
This muscle attaches onto the infraglenoid tubercle of the scapula
