The little or 'pinky' finger is ___ to the thumb.

Correct Answer: B

Rationale: The pinky is lateral (farther from midline) to the thumb, which is more medial on the hand. It's not distal (A, farther from attachment), medial, or proximal (D, closer to attachment). Lateral fits anatomy's hand orientation in anatomical position.

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.

Correct Answer: A

Rationale: The stomach is in the upper left quadrant, below the diaphragm, left of midline, unlike lower left, upper right, or lower right. Quadrant mapping in anatomy pinpoints organs for diagnosis, confirming A.
