What muscles are necessary to raise the arm above the shoulder?

The supraspinatus initiates abduction of the arm. The deltoid becomes fully effective as an abductor following the initial 15 degrees of abduction. The serratus anterior rotates the scapula, elevating its glenoid cavity so that the arm can be raised above the shoulder

 

Which of the following is NOT true regarding the clavicle?
(A) Its medial end is enlarged where it attaches to the sternum.
(B) Its lateral end is flat where it articulates with the humerus.
(C) The medial two-thirds of the shaft are convex anteriorly.
(D) The clavicle transmits shock from the upper limb to the axial skeleton.
(E) The clavicle is a “long bone” that has no medullary cavity.
The trapezius attaches to which of the following regions of the clavicle?
(A) lateral one-third of the clavicle
(B) conoid tubercle
(C) subclavian groove
(D) trapezoid line
(E) quadrangular tubercle
Which of the following is true in respect to the scapula?
(A) The spine of the scapula continues laterally as the coracoid process.
(B) The lateral surface of the scapula forms the glenoid cavity.

(C) The acromion is superior to the glenoid cavity and projects anterolaterally.
(D) The scapula is fastened securely to the thoracic cage at the scapulothoracic joint.
(E) The acromioclavicular joint represents the true shoulder joint.

Which of the following is NOT included in the condyle of the humerus?
(A) radial, coronoid, and olecranon fossae
(B) epicondyles
(C) trochlea
(D) capitulum
(E) greater tubercle
5. Which of the following is NOT true in respect to the ulna and radius?
(A) The brachialis attaches to the tuberosity of the ulna.
(B) The ulnar styloid process is much larger than the radial styloid process and extends farther distally.
(C) The head of the ulna lies distally, whereas the head of the radius articulates with the humerus.
(D) The ulna is medial to the radius in the anatomical position.
(E) The bodies of these bones are firmly bound together by the interosseous membrane.
6. Which of the following is true regarding the carpus?
(A) The scaphoid articulates proximally with the ulna and has a tubercle.
(B) The lunate articulates with the ulna and is broader anteriorly than posteriorly.
(C) The triquetrum articulates proximally with the articular disc of the distal radioulnar joint.
(D) The pisiform lies on the palmar surface of the trapezium.
(E) It is composed of seven bones.
7. Which of the following describes the correct order of the distal row of carpals from lateral to medial?
(A) triquetrum, trapezoid, capitate, hamate
(B) trapezoid, trapezium, capitate, hamate
(C) trapezium, trapezoid, capitate, hamate
(D) trapezium, triquetrum, capitate, hamate
(E) scaphoid, lunate, triquetrum, pisiform
8. Which of the following is actually a lateral cutaneous branch of an intercostal nerve, innervating the skin of the medial surface of the arm?
(A) intercostobrachial nerve
(B) superior lateral cutaneous nerve of the arm
(C) inferior lateral cutaneous nerve of the arm
(D) medial cutaneous nerve of the arm
(E) lateral pectoral nerve
9. Which of the following is NOT a branch of the radial nerve?
(A) posterior cutaneous nerve of the arm
(B) posterior cutaneous nerve of the forearm
(C) inferior lateral cutaneous nerve of the arm
(D) superior lateral cutaneous nerve of the arm
(E) posterior interosseous nerve

(B) anchors and depresses clavicle
(C) adducts and medially rotates humerus

(C) erector spinae
(D) subscapularis
(E) supraspinatus
