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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Back to Board 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.

A. DIP C. MP B. PIP D. IP Which joint of the fingers is closest to the wrist?

C. MP B. PIP Which joint of the fingers is closest to the wrist?

Back to Board MP or metacarpophalangeal joints are closer to the wrist than IP or interphalangeal joints. CM or carpometacarpal joints are closest.

A. 1 st C. 3 rd B. 2 nd D. 5 th During flexion of the MP joint of the thumb, the thumb points, generally, toward what digit?

C. 3 rd D. 5 th During flexion of the MP joint of the thumb, the thumb points, generally, toward what digit?

Back to Board Flexion of the MP joint of the thumb brings the thumb to point toward the 5th digit, generally.

Sorry, that is incorrect!
