Which of the following is NOT a specialization or characteristic of the upper limb? A. stability B. mobility C. many joints D. manipulation

Which of the following is NOT a specialization or characteristic of the upper limb? A. stability B. mobility

The upper limb is specialized for mobility, at the expense of stability, somewhat. Back to Board

The scapula moves posteriorly and medially during what action? A. abduction B. adduction C. rotation D. circumduction

The scapula moves posteriorly and medially during what action? A. abduction B. adduction

Retraction or adduction of the scapula pulls it posteriorly, when it is protracted, and medially toward the vertebral column. Back to Board

Which description is synonymous with the upward rotation of the scapula? A. depression of scapula B. elevation of scapula C. shift of scapula D. not listed

Which description is synonymous with the upward rotation of the scapula? B. elevation of scapula D. not listed

Upward rotation of the scapula moves the glenoid fossa to face superiorly. Back to Board

Which muscle is responsible for initiating abduction of the arm from one’s side? A. trapezius B. supraspinatus C. deltoid D. biceps

Which muscle is responsible for initiating abduction of the arm from one’s side? B. supraspinatus C. deltoid

Supraspinatus is responsible for the first 15 degrees of abduction of the arm, after which deltoid takes over, up to 90 degrees. Back to Board

During complete adduction of the arm, the arm moves in what directions? A. inferiorly and medially B. superiorly and laterally C. posteriorly and medially D. anteriorly and laterally

During complete adduction of the arm, the arm moves in what directions? A. inferiorly and medially C. posteriorly and medially

If the arm was first completely abducted, then it would move inferiorly and then medially in adduction back to anatomical position. Back to Board

Movement of the arm posteriorly is known as what action of the arm? A. rotation B. circumduction C. flexion D. extension

Movement of the arm posteriorly is known as what action of the arm? C. flexion D. extension

Movement of the humerus posteriorly is extension of the arm. Back to Board

With the elbow flexed, which action involves the hand moving toward the midline? A. arm extension B. arm flexion C. arm medial rotation D. arm lateral rotation

With the elbow flexed, which action involves the hand moving toward the midline? B. arm flexion C. arm medial rotation

Medial rotation of the arm brings the hand in toward the body when the elbow is flexed. Back to Board

What is the most mobile action that the shoulder can perform? A. rotation B. circumduction C. flexion D. extension

What is the most mobile action that the shoulder can perform? A. rotation B. circumduction

In circumduction, the arm circumscribes a cone in space. The glenohumeral joint is the most mobile joint in the body. Back to Board

Which muscle is NOT involved in forearm flexion? A. biceps brachii B. brachialis C. brachioradialis D. coracobrachialis

Which muscle is NOT involved in forearm flexion? C. brachioradialis D. coracobrachialis

Coracobrachialis flexes the arm, but not the forearm. Back to Board

If the brachioradialis muscle alone contracted, the hand would be in what position? A. pronation B. supination C. between pronation and supination D. flexed

If the brachioradialis muscle alone contracted, the hand would be in what position? C. between pronation and supination D. flexed

Brachioradialis returns the hand to a midpoint between pronation and supination. Back to Board

In the anatomical position with the hands supinated, flexion of the wrists points the fingertips in what direction? A. superiorly B. inferiorly C. anteriorly D. posteriorly

In the anatomical position with the hands supinated, flexion of the wrists points the fingertips in what direction? C. anteriorly D. posteriorly

In the anatomical position, the palms face forward. Flexion of the wrist points the fingertips anteriorly. Back to Board

What is another name for radial deviation? A. wrist flexion B. wrist extension C. abduction at the wrist D. adduction at the wrist

What is another name for radial deviation? C. abduction at the wrist D. adduction at the wrist

Radial deviation is abduction of the hand, and ulnar deviation is adduction. Back to Board

What is the point of reference for finger abduction and adduction? A. index finger B. middle finger C. ring finger D. thumb

What is the point of reference for finger abduction and adduction? A. index finger B. middle finger

In the hand, finger abduction and adduction takes place in reference to the middle finger. Back to Board

In the anatomical position, thumb abduction moves the thumb in what direction relative to the palm? A. anteriorly B. posteriorly C. inferiorly D. laterally

In the anatomical position, thumb abduction moves the thumb in what direction relative to the palm? A. anteriorly D. laterally

The thumb abducts at 90 degrees to the palm, so abduction moves the thumb anteriorly. Back to Board

What action of the thumb is involved in opposition? A. extension B. flexion C. adduction D. rotation

What action of the thumb is involved in opposition? B. flexion C. adduction

Opposition involves the flexion of the metacarpophalangeal and interphalangeal joints of the thumb, as well as movement of the thumb metacarpal bone toward the little finger. Back to Board
