Which of the following describes what an 'epiphysis' is?

Correct Answer: D

Rationale: The epiphysis is the end of a long bone, distinct from the diaphysis (shaft). The line is epiphyseal, membrane is periosteum. Answer is D, per the document.

Correct Answer: B

Rationale: Anatomically, hypochondriac is the abdominal region below the ribs (‘hypo’ = below, ‘chondra’ = cartilage). A is colloquial, C/D are nonsense. Answer is B, per the document.

Correct Answer: C

Rationale: Abduction moves a limb away from the midline (e.g., thigh laterally). Extension straightens, adduction moves toward, flexion bends. Answer is C, per the document.

Correct Answer: C

Rationale: Bone is living tissue with cells, blood vessels, and marrow—most blood cells are made in marrow (A), it stores minerals like calcium (B), and it protects/supports organs (D). 'Bone is a dry and non-living supporting structure' is incorrect due to its living nature.

Correct Answer: D

Rationale: Compact bone is dense with osteons, while spongy bone is porous with trabeculae—differing in cell arrangement, not marrow type, material (both hydroxyapatite), or cell size. 'They have different arrangement of bone cells' is correct.
