An action common to the teres minor and the infraspinatus muscles is _____.

external rotation

false

In the context of wrist and hand movements, radial flexion refers to the movement of the thumb side of the hand toward the medial aspect or radial side of the forearm.

false

The human wrist and hand have more than 30 muscles, of which 11 are intrinsic muscles.

false

The insertion of the pectoralis minor muscle is on the coronoid process of the scapula.

false

The olecranon process is located on the medial aspect of the ulna.

false

The origin of the rhomboid muscles is the spinous processes of the last cervical and the first seven thoracic vertebrae.

false

The scapula moves on the rib cage as a consequence of joint motion actually occurring at the acromioclavicular joint and to a lesser extent at the sternoclavicular joint.

false

The stability of the glenohumeral joint is enhanced by its significant mobility.

false

The latissimus dorsi muscle originates on the:

pronator quadratus muscle

The shoulder girdle movements primarily involve all of the following muscles except:

the pectoralis major muscle.

As the elbow reaches full extension, the olecranon process of the ulna is received by the olecranon fossa of the humerus, and this provides increased joint stability. Group starts
