The nose is ___ to the ears.

Correct Answer: C

Rationale: The nose is medial (closer to midline) to the ears, which are lateral (sides of head). It's not lateral, anterior (B, though forward of ears), or both. Medial reflects anatomy's midline reference, accurately positioning the nose centrally on the face.

Correct Answer: A

Rationale: Oral denotes the mouth, unlike mental (B, chin), buccal (C, cheek), or otic (D, ear). This term's specificity in anatomy ensures clear communication, such as in dental contexts, making A correct.

Correct Answer: A

Rationale: Sural refers to the calf (posterior lower leg), not forearm, kneecap (C, patellar), or thigh (D, femoral). This term's use in anatomy specifies regions, like sural nerve pathways, making A correct.

Correct Answer: B

Rationale: The dorsal cavity includes the cranial (brain) and vertebral (spinal cord) cavities, not ventral (A, front), abdominopelvic, or cranial alone. This posterior grouping in anatomy protects the central nervous system, making B correct.

Correct Answer: D

Rationale: The visceral pericardium covers the heart's surface, unlike parietal pleura (A, lungs), parietal pericardium (B, heart sac), or visceral peritoneum (C, abdominal organs). Visceral layers adhere to organs, a precise anatomical distinction.
