Which of the following can occur in someone reaching the exhaustion phase of the general adaptation syndrome?

Correct Answer: D

Rationale: Failed to generate a rationale of 500+ characters after 5 retries.

Correct Answer: D

Rationale: Hypothalamus produces oxytocin (labor), ADH (water balance), and releasing/inhibiting hormones (e.g., TRH, GHRH) all regulate pituitary. Oxytocin/ADH alone understate releasing hormones control anterior pituitary too. All-inclusive option distinguishes hypothalamic diversity, key to endocrine orchestration, unlike partial lists.

Correct Answer: C

Rationale: Anterior pituitary secretes growth hormone (GH, growth) and LH (luteinizing hormone, reproduction) tropic examples. ADH/oxytocin are posterior pituitary, hypothalamic-made. ACTH is anterior, but insulin is pancreatic. Thyroxine (thyroid) and cortisol (adrenal) are target gland products. GH-LH pair distinguishes anterior pituitary, key to its regulatory scope, unlike posterior or peripheral hormones.

Correct Answer: A

Rationale: Thyroid hormones (T3/T4) increase metabolic rate boosting cellular energy use, heat production. Calcitonin (thyroid) lowers calcium, not metabolism. Aldosterone (adrenal) manages sodium, not rate. PTH (parathyroid) raises calcium, minimal metabolic effect. Thyroid's metabolic surge distinguishes it, critical for energy regulation, unlike calcium or electrolyte hormones.

Correct Answer: A

Rationale: Epinephrine/norepinephrine mimic sympathetic nervous system raising heart rate, glucose, alertness fight-or-flight synergy. Parasympathetic (rest/digest) opposes slows heart, digestion focus. Somatic controls voluntary muscles, not visceral. Central (CNS) governs, not mimics. Sympathetic alignment distinguishes catecholamines, critical for stress response, unlike opposing, voluntary, or oversight systems.
