Exam 5: The Shoulder Joint

The deltoid anterior fibers are concentrically responsible for internal rotation and the deltoid posterior fibers are responsible for external rotation of the glenohumeral joint.

Which of the following is the most likely to be involved in impingement syndrome?

Which of the following muscles of the shoulder joint is located on the posterior surface of the scapula?

The coracobrachialis muscle is innervated by the musculocutaneous nerve arising from C5, C6, and C7.

Which of the following is the broadest muscle of the back and is sometimes referred to as the swimmer's muscle?

The sternal head of the pectoralis major muscle is innervated by the lateral pectoral nerve arising from C5, C6, and C7.

A concentric action common to the latissimus dorsi, teres major, and lower pectoralis major is _______.

Which of the following muscles works effectively with the latissimus dorsi in most of its concentric action and is said to be the latissimus dorsi's "little helper"?

Which of the following is the most often injured rotator cuff muscle?

Stabilization of the humeral head in the glenoid fossa is a primary action of the _______.

Which of the following is considered to be an extrinsic glenohumeral muscle?

Which of the following is not an anterior muscle of the shoulder joint?

In reaching straight across the front of the body at shoulder level to touch the anterior aspect of the contralateral with the fingers, which of the following muscles must work together?

The teres minor muscle is innervated by the axillary nerve arising from C5 and C6.

The insertion of the coracobrachialis muscle is on the coracoid process of the scapula.

Which of the following is not an intrinsic glenohumeral muscle?

Explain GIRD as to the problem with it and what should be done to correct it.

Glenohumeral joint abduction is paired with the shoulder girdle upward rotation to accomplish the total shoulder abduction range of motion.

The origin of the pectoralis major lower fibers is the anterior surface of the costal cartilages of the first six ribs, and adjoining portion of the sternum.

In the context of shoulder joint movements, abduction refers to an upward lateral movement of the humerus in the frontal plane out to the side, away from the body.
