SECTION 1: SKELETAL SYSTEM – AXIAL SKELETON (Questions
1–12)
Q1: The axial skeleton consists of which of the following bone groups?
A. Pectoral girdle, upper limbs, pelvic girdle, and lower limbs
B. Skull, vertebral column, rib cage, and hyoid bone
C. Carpals, tarsals, metacarpals, and metatarsals
D. Scapula, clavicle, pelvis, and femur
Correct Answer: B
Rationale: Correct because the axial skeleton forms the central axis of the body and is
composed of the skull, vertebral column, rib cage, and hyoid bone, totaling 80 bones.
This matches the standard anatomical classification of the axial skeleton.
Q2: Which cranial bone contains the sella turcica, which houses the pituitary gland?
A. Temporal bone
B. Occipital bone
,C. Sphenoid bone
D. Ethmoid bone
Correct Answer: C
Rationale: Correct because the sphenoid bone features the saddle-shaped sella turcica
in its body, which cradles and protects the pituitary gland. This is a critical landmark in
cranial anatomy.
Q3: The lambdoid suture joins which two bones of the skull?
A. The two parietal bones
B. The parietal bone and the occipital bone
C. The frontal bone and the parietal bones
D. The temporal bone and the parietal bone
Correct Answer: B
Rationale: Correct because the lambdoid suture is located at the posterior aspect of the
skull and specifically articulates the parietal bones with the occipital bone, forming a
lambda-shaped junction.
Q4: Which of the following is NOT a function of the vertebral column?
A. Protection of the spinal cord
B. Support of the skull and upper body
C. Attachment site for pectoral girdle muscles
D. Site of hematopoiesis within the vertebral bodies
Correct Answer: C
Rationale: Correct because the pectoral girdle (scapula and clavicle) articulates with the
axial skeleton at the sternum and indirectly via muscles, but the vertebral column does
not serve as a direct attachment site for pectoral girdle muscles; that function belongs
to the appendicular skeleton.
Q5: The cervical vertebrae are distinguished from other vertebrae by the presence of:
A. Spinous processes that are broad and plate-like
B. Transverse foramina in the transverse processes
C. Large vertebral bodies and short spinous processes
D. Articulating facets that are oriented in the coronal plane
Correct Answer: B
, Rationale: Correct because cervical vertebrae (C1–C7) uniquely possess transverse
foramina within their transverse processes, which allow passage of the vertebral
arteries and veins to and from the brain.
Q6: Which bone of the skull contains the cribriform plate, through which olfactory nerve
filaments pass?
A. Sphenoid bone
B. Ethmoid bone
C. Frontal bone
D. Nasal bone
Correct Answer: B
Rationale: Correct because the ethmoid bone contains the cribriform plate superiorly,
which is perforated by numerous foramina that transmit the olfactory nerve (CN I)
filaments from the nasal epithelium to the olfactory bulbs.
Q7: The hyoid bone is unique among bones of the axial skeleton because it:
A. Is the only bone that articulates with the mandible
B. Does not articulate with any other bone
C. Is composed entirely of compact bone
D. Contains red bone marrow for blood cell production
Correct Answer: B
Rationale: Correct because the hyoid bone is the only bone in the body that does not
form a synovial joint with any other bone; it is suspended by muscles and ligaments
from the styloid processes of the temporal bones and serves as an attachment site for
tongue muscles.
Q8: Which of the following bones contains the mastoid process, an important muscle
attachment site?
A. Temporal bone
B. Parietal bone
C. Occipital bone
D. Zygomatic bone
Correct Answer: A
