The false pelvis is

Correct Answer: C

Rationale: The false pelvis (greater pelvis) lies above the pelvic brim and is wider in females for childbirth, thus narrower in males. It’s part of the skeletal system, not inferior to the true pelvis or male-only.

Correct Answer: D

Rationale: Hyaline cartilage is avascular (lacks blood capillaries), contains cells (chondrocytes) in lacunae (spaces), but does not have prominent fibers like elastic or fibrous cartilage. Its matrix is smooth and glassy, making ‘fibres’ the correct feature it lacks.

Correct Answer: B

Rationale: Ribs, sternum, and scapulae are flat bones, characterized by their thin, broad structure. Flat bones provide protection (e.g., ribs for lungs) and surfaces for muscle attachment (e.g., scapulae). They aren’t long (elongated), short (cuboidal), or irregular (complexly shaped).

Correct Answer: B

Rationale: The sternum (breastbone) is a flat bone in the chest that, along with the ribs, forms the rib cage, primarily protecting the heart. It also shields the lungs to some extent, but its central role is heart protection. The brain is protected by the cranium, and the liver is below the diaphragm.

Correct Answer: C

Rationale: The orbits are the bony sockets in the skull that house the eyes, protecting and positioning them. The nose and ears have their own distinct structures (nasal cavity, auditory canal) separate from the orbits.
