Which of the following is NOT one of the four basic tissue types in the human body?

Correct Answer: D

Rationale: This question's phrasing suggests a trick, but all listed epithelial, connective, muscle, nervous are core tissue types. The document's 'D' answer may be an error; all are fundamental. In practice, nurses recognize these as the body's building blocks, each vital for health.

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 mitochondrion, a cell's energy producer, is an organelle, not an organ (A, tissue group), cell (C, whole unit), or tissue (D, cell group). Organelles are anatomy's intracellular specialists, and mitochondria's role in ATP synthesis exemplifies their functional importance, making B correct.

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.
