Module 6 Lab Exam: The Axial and Appendicular Skeleton
Questions & Rationale
Section 1: Anatomy Identification (10 Questions)
Q1: On a typical vertebra, the large, round, weight-bearing structure located anteriorly
is the:
A. Spinous process
B. Transverse process
C. Vertebral body [CORRECT]
D. Vertebral foramen
Correct Answer: C
Rationale: The vertebral body is the thick, disc-shaped anterior portion of a vertebra that
bears the weight of the body. It is the largest and most anterior structure, appearing as a
solid, cylindrical mass. The spinous process (A) projects posteriorly; transverse
processes (B) project laterally; the vertebral foramen (D) is the opening posterior to the
body that houses the spinal cord.
Q2: In the human skull, the large opening at the base of the occipital bone through
which the spinal cord passes is the:
A. Foramen ovale
, B. Foramen rotundum
C. Jugular foramen
D. Foramen magnum [CORRECT]
Correct Answer: D
Rationale: The foramen magnum ("great hole") is the largest foramen in the skull,
located centrally in the occipital bone. It transmits the medulla oblongata (brainstem),
vertebral arteries, and spinal accessory nerves. The foramen ovale (A) and foramen
rotundum (B) are in the sphenoid bone and transmit cranial nerves; the jugular foramen
(C) transmits the jugular vein and cranial nerves IX-XI.
Q3: The prominent bony projection located superior and lateral to the eye socket that
forms the eyebrow ridge is the:
A. Zygomatic arch
B. Nasal bone
C. Supraorbital margin/ridge [CORRECT]
D. Temporal process
Correct Answer: C
Rationale: The supraorbital margin forms the superior rim of the orbit (eye socket) and
contains the supraorbital foramen/notch. It is the bony ridge that can be palpated
beneath the eyebrow. The zygomatic arch (A) forms the cheekbone; nasal bones (B)
form the bridge of the nose; the temporal process (D) projects from the zygomatic bone
to meet the temporal bone.
