Identify the three regions of the coxal bones.

Correct Answer: D

Rationale: The coxal bone (hip) has three regions: ilium (upper), ischium (lower posterior), and pubis (lower anterior), fusing at the acetabulum. The sacrum is separate, making 'Ilium, ischium and pubis' correct.

Correct Answer: B

Rationale: Cartilaginous joints (e.g., vertebrae via discs, rib-sternum via costal cartilage, pubic symphysis) use cartilage. Tooth sockets (gomphosis) are fibrous joints, not cartilaginous, making 'between a tooth root and its socket' correct.

Correct Answer: D

Rationale: Bowing involves flexion, bending joints (e.g., knee, hip) forward. Extension straightens, abduction moves away, and adduction moves toward the midline, making 'flexion' correct.

Correct Answer: B

Rationale: Blood cells are produced in red bone marrow, primarily in flat bones and epiphyses of long bones. Yellow marrow, mostly fat, does not produce blood cells in adults, making 'False' correct.

Correct Answer: A

Rationale: A fossa is a shallow depression on a bone (e.g., olecranon fossa), per anatomical terminology, for articulation or muscle attachment. This is correct, making 'True' the answer.
