What is the function of a tendon?

Correct Answer: B

Rationale: Tendons are fibrous tissues connecting muscles to bones, transmitting force for movement. Ligaments link bones, not muscles to ligaments or bone cells, making 'To link muscles to bones' correct.

Correct Answer: C

Rationale: The superior and middle conchae (turbinates) are projections of the ethmoid bone in the nasal cavity, aiding air filtration. The inferior concha is separate, while palatine, nasal, and maxilla bones don’t form these structures.

Correct Answer: D

Rationale: The cribriform plate, perforated for olfactory nerves, is part of the ethmoid bone. Sphenoid, maxilla, temporal, and vomer lack this structure.

Correct Answer: A

Rationale: Lordosis is an exaggerated inward curvature of the lower spine (lumbar region). Scoliosis is lateral deviation, kyphosis is outward curvature (hunchback), and spina bifida is a congenital defect, not a curvature.

Correct Answer: D

Rationale: The nasal septum is composed of hyaline cartilage, a smooth, resilient type that provides support and shape. Elastic cartilage (e.g., ear) is flexible, fibrous cartilage (e.g., intervertebral discs) is tough, and calcified cartilage is hardened—none match the nasal septum’s properties or repair needs as well as hyaline.
