SECTION 1: BONE IDENTIFICATION — AXIAL SKELETON
(Questions)
Skull Bones & Markings
1. Identify the bone that forms the forehead and roof of the
orbits.
A) Parietal bone
B) Frontal bone
C) Temporal bone
D) Occipital bone
,Correct Answer: B
Rationale: The frontal bone forms the forehead (the anterior
part of the cranium), the roofs of the orbits, and most of the
anterior cranial fossa. It articulates with the parietal bones at
the coronal suture.
2. Identify the bone that forms the lower sides and base of the
cranium.
A) Frontal bone
B) Parietal bone
C) Temporal bone
D) Occipital bone
Correct Answer: C
Rationale: The temporal bone forms the lower sides and base
of the cranium. It contains the external acoustic meatus,
mastoid process, styloid process, and zygomatic process.
3. Identify the bone that forms the back of the head and the
base of the skull.
A) Frontal bone
B) Temporal bone
C) Parietal bone
D) Occipital bone
Correct Answer: D
Rationale: The occipital bone forms the back of the head and
,the base of the skull. It contains the foramen magnum, through
which the spinal cord connects to the brain.
4. The large opening at the base of the skull through which the
spinal cord passes is the:
A) Foramen ovale
B) Foramen magnum
C) Jugular foramen
D) Carotid canal
Correct Answer: B
Rationale: The foramen magnum is the large opening at the
base of the occipital bone through which the brain connects to
the spinal cord.
5. The smooth area of the frontal bone between the eyes is
the:
A) Glabella
B) Supraorbital margin
C) Frontal sinus
D) Coronal suture
Correct Answer: A
Rationale: The glabella is the smooth, slightly depressed area of
the frontal bone between the supraorbital margins (between
the eyebrows).
6. The bony projection behind the ear that serves as an
attachment point for neck muscles is the:
, A) Styloid process
B) Mastoid process
C) Zygomatic process
D) External acoustic meatus
Correct Answer: B
Rationale: The mastoid process is a bony projection of the
temporal bone located posterior to the external acoustic
meatus (ear canal). It provides attachment for several neck
muscles.
7. The sharp, needle-like projection of the temporal bone that
serves as an attachment point for tongue and hyoid muscles is
the:
A) Mastoid process
B) Styloid process
C) Zygomatic process
D) Mandibular fossa
Correct Answer: B
Rationale: The styloid process is a sharp, needle-like projection
of the temporal bone. It serves as an attachment point for
muscles of the tongue, pharynx, and hyoid bone.
8. The cheekbone is formed by the:
A) Maxilla
B) Zygomatic bone
