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: 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.

Correct Answer: D

Rationale: The axial skeleton includes the skull (22 bones), vertebral column (26 bones), ribs (24 bones), and sternum (1 bone), totaling 80 bones. The appendicular skeleton has 126 bones, making 90 and 126 incorrect, and 60 too low for the axial components.

Correct Answer: A

Rationale: Ligaments are fibrous connective tissues that connect bones to other bones, stabilizing joints (e.g., in the knee or ankle). This distinguishes them from tendons (muscle to bone), making ‘True’ the correct answer.

Correct Answer: B

Rationale: Sutures are the serrated, immovable joints connecting cranial bones, such as the coronal or sagittal sutures. 'Sews' and 'stitches' relate to sewing, not anatomy, making 'sutures' the precise term.
