Which one of the following statements is accurate for the Axial Skeleton?

Correct Answer: B

Rationale: The axial skeleton includes 80 bones (skull, vertebral column, thoracic cage) in the central body, not extremities. The appendicular has 126 bones at extremities. '100' and '126' are incorrect, making 'Consists of 80 bones which are located in the upper central part of the body' accurate.

Correct Answer: D

Rationale: The elbow is a hinge joint, allowing flexion and extension in one plane. The hip and shoulder are ball-and-socket, and the ribcage has slightly movable joints, making 'Elbow' correct.

Correct Answer: B

Rationale: The occipital bone, at the skull’s base, is the most superior in anatomical position (topmost). The manubrium (sternum top) is chest-level, cervical vertebra #3 is mid-neck, and patella is knee-level. Answer is B, per the document.

Correct Answer: B

Rationale: Osteocytes reside in lacunae, small pits in bone matrix (compact or spongy). Haversian canals hold vessels, trabeculae are spongy structures, and endosteum lines cavities—not homes for osteocytes. Answer is B, per the document.

Correct Answer: A

Rationale: A tuberosity is a projection for muscle attachment, not a depression. Facet (flat surface), meatus (tube), and sinus (cavity) are depressions/cavities. Answer is A, per the document.
