Which of the following is NOT a 'long' bone?

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: B

Rationale: The lateral condyle of the femur articulates with the tibia at the knee joint. Tuberosity, trochanter, and tubercle are muscle attachments, not articulations. Answer is B, per the document.

Correct Answer: D

Rationale: Osteoclasts reabsorb bone, breaking it down. Osteons are structures, osteoblasts form bone, osteocytes maintain it. Answer is D, per the document (note: text error corrected—osteoblast matures to osteocyte, not osteoclast).

Correct Answer: B

Rationale: Appendicular skeleton includes pectoral girdle, phalanges, and lower limbs. Thoracic cage (ribs, sternum) is axial. Answer is B, per the document.

Correct Answer: A

Rationale: Haemopoiesis is blood cell formation in bone marrow (‘poiesis’ = making). Clotting is haemostasis, crenation is osmotic, and proportion isn’t haemopoiesis. Answer is A, per the document.
