Which of the following is an example of negative feedback?

Correct Answer: D

Rationale: Negative feedback stabilizes variables by reversing deviations blood pressure adjusts to exertion, glucose balances after meals, and pH corrects via breathing or kidney action. Each counters change to maintain set points, a common regulatory theme. Nurses manage these like insulin for glucose relying on this mechanism's prevalence to restore equilibrium, distinguishing it from amplifying processes and ensuring bodily consistency across systems.

Correct Answer: D

Rationale: The antebrachium is the forearm (elbow to wrist), not chest, hand, shoulder, or arm broadly (D, brachium). Anatomical terms pinpoint regions antebrachial arteries supply this area ensuring precision.

Correct Answer: B

Rationale: Hormones regulate distantly via blood (e.g., insulin), unlike cells, ions, impulses (D, nerves), or neurotransmitters (E, synapses). Anatomically, endocrine glands (e.g., thyroid) use hormones for homeostasis, confirming B.

Correct Answer: C

Rationale: The diaphragm's upper surface faces parietal pleura (thoracic), lower faces parietal peritoneum (abdominal). Visceral layers (A, B, D) cover organs, not cavity walls. Anatomically, parietal membranes line cavities above and below the diaphragm, reducing friction, making C correct.

Correct Answer: B

Rationale: Gross anatomy examines organs and tissues visibly, without microscopes, unlike microscopic anatomy , histology (C, tissue microscopy), or cytology (D, cell microscopy). Per options A5-A8, it's macroscopic e.g., dissecting a liver by hand. Anatomically, it's foundational for surgery, contrasting with microscopic fields, making B correct.
