,1. A forensic anthropologist examines an adult pelvis and notes that the subpubic angle is
wide and the greater sciatic notch is broad. Which additional pelvic feature would most
strongly support a female identification?
[ ] A. Narrow, heart-shaped pelvic inlet
[ ] B. Preauricular sulcus on the ilium
[ ] C. Sacrum with pronounced ventral concavity and greater height
[ ] D. Obturator foramen that is small and oval
CORRECT: B. Preauricular sulcus on the ilium
The preauricular sulcus, a groove adjacent to the auricular surface of the ilium, is a classic female pelvic trait
linked to ligamentous laxity during pregnancy. A narrow heart-shaped inlet, a long ventrally concave sacrum,
and small oval obturator foramina are male characteristics.
2. During a lab practical, a student must identify a vertebra with a foramen transversarium
but no costal facet on the body. Which vertebra is being described?
[ ] A. T1
[ ] B. C7
[ ] C. T12
[ ] D. L1
CORRECT: B. C7
Cervical vertebrae are uniquely identified by the foramen transversarium. C7 is the only typical cervical
vertebra lacking a costal facet on the body, though it may possess a small costal facet on the transverse
process. T1 and T12 are thoracic and bear costal facets; L1 is lumbar and lacks transverse foramina.
3. A hiker falls and fractures the lateral malleolus. Which bone is involved, and which
structure does it articulate with?
[ ] A. Tibia; articulates with the talus
[ ] B. Fibula; articulates with the talus
[ ] C. Calcaneus; articulates with the navicular
[ ] D. Tibia; articulates with the calcaneus
CORRECT: B. Fibula; articulates with the talus
The lateral malleolus is the distal expansion of the fibula and forms the lateral wall of the ankle mortise,
articulating with the lateral surface of the talus. The medial malleolus belongs to the tibia, and the calcaneus
does not articulate with the tibia.
4. Which statement correctly describes the structural relationship between the axial and
appendicular skeletons at the sternoclavicular joint?
[ ] A. The clavicle articulates with the manubrium and the first costal cartilage, anchoring the
HIGHP - Page 2 of 45
, appendicular girdle to the axial skeleton.
[ ] B. The clavicle articulates only with the body of the sternum, providing no connection to the axial
skeleton.
[ ] C. The clavicle articulates with the xiphoid process and the second rib, forming a synchondrosis.
[ ] D. The clavicle articulates with the manubrium via a fibrous suture, allowing no movement.
CORRECT: A. The clavicle articulates with the manubrium and the first costal cartilage, anchoring
the appendicular girdle to the axial skeleton.
The sternoclavicular joint is the only true synovial articulation between the appendicular and axial skeletons; it
involves the manubrium and the first costal cartilage. It is not a suture or synchondrosis, and it does not
involve the xiphoid process or the sternal body alone.
5. A defect in intramembranous ossification would most directly impair the development
of which structure?
[ ] A. Femoral diaphysis
[ ] B. Vertebral body
[ ] C. Flat bones of the skull
[ ] D. Costal cartilage
CORRECT: C. Flat bones of the skull
Intramembranous ossification forms flat bones such as the frontal and parietal bones directly from
mesenchyme. The femoral diaphysis and vertebral bodies form through endochondral ossification, and costal
cartilage remains hyaline cartilage.
6. Which feature distinguishes the second cervical vertebra (axis) from all other
vertebrae?
[ ] A. Bifid spinous process
[ ] B. Dens (odontoid process)
[ ] C. Large heart-shaped body
[ ] D. Costal facets on the body
CORRECT: B. Dens (odontoid process)
The dens, or odontoid process, is a unique upward projection of the axis that articulates with the anterior arch
of the atlas, permitting head rotation. Bifid spinous processes occur in typical cervical vertebrae, while
heart-shaped bodies and costal facets are thoracic features.
7. A radiograph shows a fracture traversing the cribriform plate. Which bone is fractured,
and which special sense is most at risk?
[ ] A. Ethmoid bone; olfaction
[ ] B. Sphenoid bone; vision
HIGHP - Page 3 of 45
, [ ] C. Temporal bone; hearing
[ ] D. Frontal bone; taste
CORRECT: A. Ethmoid bone; olfaction
The cribriform plate is part of the ethmoid bone and contains olfactory foramina through which olfactory nerve
filaments pass, so olfaction is at risk. The sphenoid, temporal, and frontal bones do not contain the cribriform
plate.
8. Which of the following best explains why the intervertebral discs are thicker in the
lumbar region than in the thoracic region?
[ ] A. To allow greater flexibility and shock absorption in the lower back
[ ] B. To provide attachment sites for the ribs
[ ] C. To accommodate the larger spinal cord in the lumbar region
[ ] D. To fuse the lumbar vertebrae into a single unit
CORRECT: A. To allow greater flexibility and shock absorption in the lower back
Thicker lumbar discs permit the greater range of motion and weight-bearing shock absorption required by the
lower back. Rib attachment is thoracic, the spinal cord ends at about L1-L2, and lumbar vertebrae are not
fused.
9. During a lab, a student observes a bone marking described as a large, rounded, smooth
articular projection on the proximal femur. Which term correctly identifies this marking?
[ ] A. Trochanter
[ ] B. Condyle
[ ] C. Head
[ ] D. Tuberosity
CORRECT: C. Head
The head of the femur is a large, rounded, smooth articular projection that fits into the acetabulum. A
trochanter is a large blunt projection, a condyle is a rounded articular process (e.g., femoral condyles), and a
tuberosity is a rounded non-articular elevation.
10. Which bone of the appendicular skeleton articulates with the trapezium and the
capitate?
[ ] A. Scaphoid
[ ] B. Lunate
[ ] C. First metacarpal
[ ] D. Triquetrum
