Question 1
Which type of bone is characterized by a shaft with expanded ends and is
found in the extremities?
A. Long bone
B. Short bone
C. Flat bone
D. Irregular bone
Answer: A
Rationale: Long bones are characterized by a shaft (diaphysis) with
expanded ends (epiphyses) and are found in the extremities (e.g.,
femur, humerus). Short bones (B) are cube-shaped (e.g., carpals).
Flat bones (C) are thin and flattened (e.g., sternum). Irregular bones
(D) have complex shapes (e.g., vertebrae).
Question 2
Which type of muscle is under voluntary control?
A. Skeletal muscle
B. Cardiac muscle
,C. Smooth muscle
D. All of the above
Answer: A
Rationale: Skeletal muscle is under voluntary control, while cardiac
and smooth muscles are involuntary. Cardiac muscle (B) is
involuntary. Smooth muscle (C) is involuntary. All of the above (D) is
incorrect.
Question 3
Which structure connects muscle to bone?
A. Ligament
B. Tendon
C. Cartilage
D. Bursa
Answer: B
Rationale: Tendons connect muscle to bone. Ligaments (A) connect
bone to bone. Cartilage (C) provides cushioning. Bursa (D) reduces
friction.
Question 4
What is the name of the connective tissue sheath that surrounds
individual muscle fibers?
A. Epimysium
B. Perimysium
C. Endomysium
D. Fascia
,Answer: C
Rationale: Endomysium surrounds individual muscle fibers.
Epimysium (A) surrounds the entire muscle. Perimysium (B)
surrounds fascicles. Fascia (D) is a broader connective tissue.
Question 5
Which cell type is responsible for bone resorption?
A. Osteoblast
B. Osteoclast
C. Osteocyte
D. Chondrocyte
Answer: B
Rationale: Osteoclasts resorb bone. Osteoblasts (A) form bone.
Osteocytes (C) are mature bone cells. Chondrocytes (D) are
cartilage cells.
Question 6
Which vitamin is essential for calcium absorption and bone
mineralization?
A. Vitamin A
B. Vitamin C
C. Vitamin D
D. Vitamin K
Answer: C
Rationale: Vitamin D is essential for calcium absorption and bone
, mineralization. Vitamin A (A) is for vision. Vitamin C (B) is for
collagen synthesis. Vitamin K (D) is for clotting.
Question 7
What is the primary function of the meniscus in the knee?
A. Shock absorption
B. Lubrication
C. Proprioception
D. All of the above
Answer: D
Rationale: The meniscus provides shock absorption, lubrication, and
proprioception.
Question 8
Which muscle is the primary flexor of the elbow?
A. Triceps
B. Biceps
C. Brachialis
D. Brachioradialis
Answer: C
Rationale: The brachialis is the primary flexor of the elbow. The
biceps (B) is a secondary flexor and supinator. The triceps (A) is the
extensor. The brachioradialis (D) is a flexor but less powerful.
Question 9
Which nerve is most commonly injured in a midshaft humerus fracture?
