Answer 21

TRUE

Question 22

The median nerve supplies all the intrinsic muscles of the hand.

Answer 23

False (It contains the radial artery and the superficial branch of the radial nerve)

Question 24

The extensor pollicis longus is an intrinsic muscle of the hand.

Answer 24

False (It is an extrinsic muscle located in the forearm)

Question 25

The hand has three types of joints: metacarpophalangeal, interphalangeal, and carpometacarpal joints.

Answer 25

TRUE

Question 26

The palmar venous arches receive blood from the dorsal venous network of the hand.

Answer 26

False (The dorsal venous network drains into the cephalic and basilic veins, while the palmar venous arches receive blood from the palmar metacarpal and digital veins)

Question 27

The abductor pollicis longus originates from the ulna and radius and inserts into the base of the first metacarpal.

Answer 27

TRUE

Question 28

The radial nerve provides cutaneous innervation to the medial side of the hand.

Answer 28

False (The radial nerve provides cutaneous innervation to the lateral side of the hand, while the ulnar nerve supplies the medial side)

Question 29

The scaphoid bone is the most commonly fractured carpal bone.

Answer 29

TRUE

Question 30

The anatomical snuffbox is more visible when the thumb is abducted and extended.

Answer 30

TRUE

Question 31

The ulnar nerve passes through the carpal tunnel

Answer 31

False (The median nerve passes through the carpal tunnel)

Question 32

The hand's intrinsic muscles are primarily responsible for gross movements.

Answer 32

False (The intrinsic muscles are responsible for fine movements, while the extrinsic muscles handle gross movements)

Question 33

The flexor digitorum superficialis muscle is an extrinsic muscle that plays a key role in finger movement.

Answer 33

TRUE

Question 34

The radial artery forms both the superficial and deep palmar arches.

Answer 34

False (The ulnar artery contributes to the superficial palmar arch, while the radial artery contributes to the deep palmar arch)

Question 35

The extensor pollicis longus tendon passes through the anatomical snuffbox.

Answer 35

TRUE

Question 36

The hand contains only two types of phalanges: proximal and distal.

Answer 36

False (The hand contains proximal, middle, and distal phalanges, except for the thumb, which has only two phalanges)

Question 37

The median nerve is responsible for sensation in the thumb, index finger, and middle finger.

Answer 37

TRUE

Question 38

The anatomical snuffbox is located on the medial side of the wrist.

Answer 38

False (It is located on the lateral side of the wrist)

Question 39

The palmaris longus muscle is an important flexor of the wrist.

Answer 39

TRUE

Question 40

The ulnar nerve supplies sensation to the lateral two lumbricals.

Answer 40

False (The ulnar nerve supplies the medial two lumbricals, while the radial nerve supplies the lateral two lumbricals)

Question 41

The ulnar nerve passes between the anterior and posterior bands of the ulnar collateral ligament at the elbow joint.

Answer 41

TRUE

Question 42

The flexor retinaculum attaches to the pisiform bone

Answer 42

False (It attaches to the scaphoid, hamate, trapezium, and capitate, but not the pisiform.)

Question 43

The radial nerve is palpable over the tendons in the anatomical snuffbox.

Answer 43

TRUE

Question 44

The cephalic vein begins in the roof of the anatomical snuffbox.

Answer 44

TRUE

Question 45

The clavicle is the first bone to ossify in the fetus.

Answer 45

fetus

Question 46

The ulnar nerve makes contact with the periosteum of the humerus.

The radial artery forms both the anterior and posterior carpal arches.

Answer 47

TRUE

Question 48

The ulnar nerve is a continuation of the medial cord of the brachial plexus.

Answer 48

TRUE

Question 49

The anatomical snuffbox contains the radial styloid, scaphoid, trapezium, and the base of the first metacarpal bone.

Answer 49

TRUE
