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
Which joint of the fingers is closest to the wrist?
A. DIP
B. PIP
C. MP
D. IP
Which joint of the fingers is closest to the wrist?
B. PIP
C. MP
MP or metacarpophalangeal joints are closer to the wrist than
IP or interphalangeal joints. CM or carpometacarpal joints
are closest.
