Which of the following is actually a lateral cutaneous branch of an intercostal nerve, innervating the skin of the medial surface of the arm?
The intercostobrachial nerve is the lateral cutaneous branch of the second intercostal nerve from T2, innervating the skin of the medial surface of the arm
Which of the following is NOT true in respect to the ulna and radius?
The radial styloid process is much larger than the ulnar styloid process and extends farther distally
Which of the following is NOT included in the condyle of the humerus?
The condyle of the humerus (the distal end) includes the epicondyles, trochlea, capitulum, and the three fossae (radial, coronoid, and radial)
Which of the following best describes the action of the pectoralis minor?
The pectoralis minor stabilizes the scapula by drawing it inferiorly and anteriorly against the thoracic wall
Which of the following is NOT a branch of the radial nerve?
The posterior cutaneous nerve of the arm, posterior cutaneous nerve of the forearm, and inferior lateral cutaneous nerve of the arm are branches of the radial nerve. The superior lateral cutaneous nerve is a branch of the axillary nerve
Which of the following is innervated by the dorsal scapular nerve?
The dorsal scapular nerve innervates the levator scapulae, rhomboid major, and rhomboid minor
Which of the following muscles attaches to the coracoid process of the scapula?
The pectoralis minor, biceps brachii (short head), and coracobrachialis attach to the coracoid process of the scapula
The trapezius attaches to which of the following regions of the clavicle?
The trapezius attaches to the lateral third of the clavicle, acromion, and spine of the scapula. The deltoid attaches to the deltoid tubercle, the conoid ligament attaches to the conoid tubercle, the subclavius attaches to the subclavian groove, and the trapezoid ligament attaches to the trapezoid line
Which of the following is true in respect to the scapula?
The lateral surface of the scapula forms the glenoid cavity, superior to which the coracoid process projects anterolaterally. The glenohumeral joint itself represents the true shoulder joint, whereas the scapulothoracic joint, which is a conceptual joint, is a location where the scapula moves easily on the thoracic wall. The spine of the scapula continues laterally as the acromion
Which of the following is true regarding the carpus?
The scaphoid articulates proximally with the radius and has a large tubercle. The lunate articulates with the radius and is broader anteriorly than posteriorly. The triquetrum articulates proximally with the articular disc of the distal radioulnar joint. The pisiform lies on the palmar surface of the triquetrum
Which of the following is NOT an anterior thoracoappendicular muscle?
The pectoralis major, pectoralis minor, subclavius, and serratus anterior are anterior thoracoappendicular muscles. The deltoid is a scapulohumeral (shoulder) muscle
Which of the following is NOT true regarding the clavicle?
The lateral end of the clavicle is flat where it articulates with the acromion at the acromioclavicular (AC) joint
Which of the following describes the correct order of the distal row of carpals from lateral to medial?
From lateral to medial, the four bones of the distal row of carpals are the trapezium, trapezoid, capitate, and hamate
All of the following are medial rotators of the arm EXCEPT
Please select 2 correct answers
The latissimus dorsi, teres major, and subscapularis medially rotate the arm. The infraspinatus and teres minor rotate the arm laterally. The deltoid is unique in that its anterior part rotates the arm medially, and its posterior part rotates the arm laterally
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
