ANSWERS.
1. The parietal bone is an example of a _______ bone.
A) Long
B) Short
C) Irregular
D) Sesamoid
Correct Answer: C) Irregular
Rationale: Irregular bones have complex shapes and include vertebrae, hip bones, and
several skull bones such as the parietal bone. Long bones (femur, humerus) have a shaft
and two ends; short bones (carpals, tarsals) are roughly cube-shaped; sesamoid bones
(patella) develop within tendons.
2. In the epiphyseal plate, cartilage grows:
A) From the diaphysis to the epiphysis
B) From the epiphysis to the diaphysis
C) From the edges inward
D) In a circular fashion
, Correct Answer: B) From the epiphysis to the diaphysis
Rationale: The epiphyseal (growth) plate is organized into zones. Chondrocytes proliferate
and mature in the zone nearest the epiphysis, pushing the epiphysis away from the
diaphysis as new cartilage is formed on the epiphyseal side and replaced by bone on the
diaphyseal side, allowing for longitudinal bone growth.
3. The suture that connects the parietal bone with the frontal bone is the _______
suture.
A) Sagittal
B) Coronal
C) Squamous
D) Lambdoid
Correct Answer: B) Coronal
Rationale: The coronal suture runs horizontally across the skull and connects the frontal
bone with the two parietal bones. The sagittal suture connects the two parietal bones;
squamous connects temporal and parietal bones; lambdoid connects occipital and parietal
bones.
4. The structure that separates the condylar and coronoid processes of the
mandible is the:
A) Mandibular ramus
B) Mandibular angle
C) Styloid process
, D) Mandibular notch
E) Mandibular canal
Correct Answer: D) Mandibular notch
Rationale: The mandibular notch is the U-shaped depression between the condylar process
(which articulates with the temporal bone at the TMJ) and the coronoid process
(attachment site for temporalis muscle). The ramus is the vertical portion of the mandible;
the angle is where the ramus meets the body.
5. Which of the following statements is/are TRUE?
A) Ribs numbered 11 and 12 are true ribs because they have no anterior attachments
B) The most common site of fracture in the humerus is the anatomical neck
C) In anatomical position, the lateral forearm bone is the ulna
D) Each vertebral disc possesses a nucleus pulposus and an annulus fibrosus
E) C and D
Correct Answer: D) Each vertebral disc possesses a nucleus pulposus and an
annulus fibrosus
Rationale: Intervertebral discs consist of an outer annulus fibrosus (concentric rings of
fibrocartilage) and inner nucleus pulposus (gelatinous core). Ribs 11 and 12 are
false/floating ribs (no anterior attachment). The surgical neck (not anatomical neck) is the
common fracture site in the humerus. In anatomical position, the radius is lateral and the
ulna is medial in the forearm.
, 6. The prominent bulge just posterior and inferior to the external auditory meatus
is the:
A) Maxillary bone
B) Lacrimal bone
C) Occipital bone
D) Mastoid process
E) External occipital protuberance
Correct Answer: D) Mastoid process
Rationale: The mastoid process is a bony projection of the temporal bone located posterior
and inferior to the external auditory meatus. It serves as an attachment site for several
neck muscles (sternocleidomastoid, splenius capitis, longissimus capitis) and contains air
cells. This landmark is easily palpable on oneself.
7. The meatus can best be described as a:
A) Large bony prominence
B) Tube-like opening or channel
C) Shallow groove
D) Raised, rough area
Correct Answer: B) Tube-like opening or channel
Rationale: A meatus is a tubular passage or channel through bone. Examples include the
external acoustic meatus (ear canal) and the internal acoustic meatus (passage for cranial
nerves VII and VIII). A large prominence is a tuberosity or trochanter; a shallow groove is a
sulcus; a raised rough area is a tubercle.
