,Chapter 1. Anatomy and Kinesiology of the Hand
1. Which of the following bones is NOT part of the carpal bones in the wrist?
A. Scaphoid
B. Lunate
C. Proximal phalanx
D. Trapezium
Correct Answer: C. Proximal phalanx
Rationale: The proximal phalanx is part of the finger bones (phalanx), while the carpal bones include the
scaphoid, lunate, trapezium, and others.
2. Select all that apply: Which of the following structures are responsible for the intricate
movements of the hand?
A. Flexor tendons
B. Extensor tendons
C. Ligaments
D. Muscles of the forearm
Correct Answer: A, B, C, D
Rationale: All these structures contribute to the mobility and functionality of the hand.
3. What is the primary function of the flexor retinaculum?
A. To stabilize the wrist
B. To create an anatomical tunnel for the median nerve
C. To facilitate finger extension
D. To connect the forearm muscles
Correct Answer: B. To create an anatomical tunnel for the median nerve
Rationale: The flexor retinaculum forms the roof of the carpal tunnel, protecting the median nerve and
flexor tendons.
4. In terms of biomechanics, what is the main role of the thumb in hand function?
A. To provide opposition
B. To enhance grip strength
C. To increase range of motion
D. To stabilize the wrist
Correct Answer: A. To provide opposition
Rationale: Opposition is the ability to touch the thumb to the other fingers, allowing for grasping and
manipulation of objects.
5. Which muscle primarily performs flexion at the metacarpophalangeal (MCP) joint of the thumb?
A. Extensor pollicis longus
B. Flexor pollicis brevis
C. Abductor pollicis longus
D. Opponens pollicis
,Correct Answer: B. Flexor pollicis brevis
Rationale: The flexor pollicis brevis is crucial for flexing the thumb at the MCP joint.
6. What is the significance of the triangular fibrocartilage complex (TFCC)?
A. It provides cushioning to the metacarpophalangeal joints.
B. It facilitates wrist motion and stability.
C. It connects the wrist bones to the forearm.
D. It acts as a primary flexor of the wrist.
Correct Answer: B. It facilitates wrist motion and stability.

B. De Quervain's tenosynovitis
C. Trigger finger
D. Dupuytren's contracture
Correct Answer: A, B, C
Rationale: All listed conditions except Dupuytren's contracture are typically due to overuse, involving
inflammation and dysfunction in the hand and wrist.
8. What is the primary movement allowed at the interphalangeal (IP) joints of the fingers?
A. Flexion and extension
B. Adduction and abduction
C. Opposition and reposition
D. Rotation
Correct Answer: A. Flexion and extension
Rationale: The interphalangeal joints primarily allow flexion and extension, permitting the bending and
straightening of fingers.
9. In anatomical terms, what is the position of the hand in "palmar" orientation?
A. With the palm facing forward
B. With the dorsal part facing forward
C. With fingers extended
D. With the wrist in ulnar deviation
Correct Answer: A. With the palm facing forward
Rationale: The palmar orientation refers to the position where the palm is facing forward or upwards in
anatomical position.
10. Which ligament provides support to the ulnar side of the wrist?
A. Radial collateral ligament
B. Palmar radiocarpal ligament
, C. Ulnar collateral ligament
D. Dorsal radiocarpal ligament
Correct Answer: C. Ulnar collateral ligament
Rationale: The ulnar collateral ligament supports the ulnar side of the wrist to maintain stability during
activities.
11. Which of the following is a primary action of the lumbrical muscles?
A. Extension of the fingers
B. Flexion of the fingers at the MCP joints
C. Abduction of the fingers
D. Opposition of the thumb
Correct Answer: B. Flexion of the fingers at the MCP joints
Rationale: The lumbricals flex the fingers at the MCP joints while allowing for extension at the distal
interphalangeal (DIP) joints.
12. What is the main anatomical feature of the metacarpals that enhances grip strength?
A. Proximal bases
B. Distal heads
C. Curvature
D. Ligamentous attachments
Correct Answer: C. Curvature
Rationale: The curvature of metacarpals enhances grip strength and allows for better hand function
during grasping tasks.
13. Select all that apply: Which tendons pass through the carpal tunnel?
A. Flexor digitorum superficialis
B. Flexor pollicis longus
C. Palmaris longus
D. Flexor digitorum profundus
Correct Answer: A, B, D
Rationale: Flexor digitorum superficialis, flexor pollicis longus, and flexor digitorum profundus tendons
pass through the carpal tunnel. The palmaris longus does not.
14. Which nerve is primarily affected by carpal tunnel syndrome?
A. Ulnar nerve
B. Median nerve
C. Radial nerve
D. Musculocutaneous nerve
Correct Answer: B. Median nerve
Rationale: Carpal tunnel syndrome involves compression of the median nerve, leading to symptoms in
the thumb, index, middle, and part of the ring finger.
15. The term "prehension" in hand function refers to what?
A. The ability to perform fine motor tasks.
