A group of similar types of cells that performs a specific function is a(n):

Correct Answer: D

Rationale: A tissue is a group of similar cells with a specific function, like muscle tissue contracting. An organism is a whole living entity, an organelle is a cell component (e.g., nucleus), and an organ combines tissues. Tissues are the second organizational level after cells, foundational in anatomy for understanding how specialized functions like epithelial tissue protecting skin build complex structures.

Correct Answer: B

Rationale: The calf is distal (farther from attachment) to the knee, which is proximal (closer to thigh attachment). It's not deep (A, depth-related), proximal, or both. Distal aligns with anatomy's limb terminology, marking the calf below the knee.

Correct Answer: D

Rationale: Muscles are deep (beneath) the skin, which is superficial (surface). They're not lateral (A, side), superficial, or superior (C, above). Depth terms in anatomy clarify layering, like muscles under skin, essential for understanding body structure.

Correct Answer: C

Rationale: Axillary refers to the armpit, not acromial (A, shoulder), brachial (B, arm), or sternal (D, chest). Anatomical terms like axillary pinpoint regions, vital for procedures like lymph node checks, confirming C.

Correct Answer: D

Rationale: The sagittal plane divides left and right (e.g., midsagittal at midline), unlike coronal/frontal (A, B, front-back), or transverse (C, top-bottom). Anatomical planes standardize sectioning, vital for imaging like MRI, confirming D.
