Which one of the following bones is not part of the Appendicular Skeleton?

Correct Answer: C

Rationale: The appendicular skeleton comprises the limbs and girdles, including the clavicle (pectoral girdle), humerus (arm), and radius (forearm). The cranium (skull) is part of the axial skeleton, making 'Cranium' the correct answer for what is not appendicular.

Correct Answer: D

Rationale: The spine (vertebral column) has intervertebral discs, making its joints (e.g., between vertebrae) slightly movable (amphiarthroses). The skull is fixed, clavicle and pelvis have synovial joints, making 'Spine' correct.

Correct Answer: A

Rationale: Haemopoiesis (blood cell formation) occurs in bone marrow, producing red and white blood cells. Haemostasis is blood clotting, peristalsis is digestive movement, and glycogenolysis is glucose breakdown—none are skeletal functions. Answer is A, as per the document.

Correct Answer: C

Rationale: Long bones are longer than wide (e.g., humerus, tibia, metacarpals). Carpals (wrist bones) are short bones, roughly cube-shaped, not long. Answer is C, per the document.

Correct Answer: A

Rationale: Pronation/supination occur in the forearm, with radius rotating over ulna. Foot does inversion/eversion, thigh and wrist don’t pronate/supinate. Answer is A, per the document.
