Place the levels of organization in order from least complex to most complex.

Correct Answer: B

Rationale: The correct order is atom (smallest), molecule, organelle, cell, tissue, organ, organ system, organism (most complex). B aligns with this, starting with atoms forming molecules (e.g., water), then organelles (e.g., ribosomes), cells, tissues (e.g., muscle), organs (e.g., heart), systems (e.g., circulatory), and organisms (e.g., human). Other options misplace levels, disrupting anatomy's logical progression.

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: 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.
