Which gland is often referred to as the 'master gland' because it controls other endocrine glands?

Correct Answer: C

Rationale: The pituitary gland, dubbed the 'master gland,' orchestrates other endocrine functions, like thyroid activity, via hormone signals. Unlike standalone glands, it's a regulatory hub. Clinicians target it in hormonal disorders, leveraging its oversight to correct systemic imbalances.

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: Parathyroid hormone (PTH) adjusts blood calcium, mobilizing it from bones when low. Unlike metabolic or sex hormones, it's a calcium gatekeeper. Nurses monitor it in bone health like osteoporosis ensuring skeletal and systemic balance.

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.
