This hormone is not secreted by Hypothalamus

Correct Answer: B

Rationale: The hypothalamus secretes releasing hormones like PRH (prolactin), CRH (corticotropin), and TRH (thyrotropin) not FSH, which the anterior pituitary produces under hypothalamic GnRH control. This distinction clarifies hypothalamic regulatory roles, vital for NEET's pituitary-hypothalamic axis understanding, contrasting with pituitary effectors.

Correct Answer: A

Rationale: The thyroid, in the neck, is the largest purely endocrine gland by mass, secreting thyroxine and calcitonin for metabolism and calcium regulation. Pituitary, small but master, controls others. Adrenals produce steroids and catecholamines, smaller than thyroid. Pancreas, larger, is dual endocrine (islets) and exocrine (digestion), diluting its endocrine claim. Thyroid's size and exclusive endocrine role distinguish it, vital for systemic metabolism.

Correct Answer: B

Rationale: Polydipsia (excessive thirst) is a diabetes mellitus symptom, driven by hyperglycemia dehydrating cells, triggering thirst. 'Glyconemia' isn't a term hyperglycemia is correct, but not listed. Weight gain contrasts with typical loss from glucose wasting. Hypoglycemia isn't characteristic high glucose defines it. Polydipsia's link to osmotic diuresis distinguishes it, key to diabetes recognition, unlike misnamed or opposing signs.

Correct Answer: D

Rationale: Post-subtotal thyroidectomy, removing most thyroid tissue, the nurse monitors hypothyroidism (low T₃/T₄) and the nearby parathyroid glands, embedded in the thyroid, which regulate calcium via parathyroid hormone (PTH). Surgical disruption risks hypoparathyroidism, causing hypocalcemia (e.g., tetany). Pituitary oversees TSH but isn't local or directly affected here. Pancreas (insulin) and adrenals (cortisol) are distant, unrelated to thyroid proximity. Parathyroids' anatomical closeness and calcium role distinguish them, critical for post-surgical care, unlike systemic or distant glands.

Correct Answer: C

Rationale: Endocrine glands produce hormones chemical messengers like insulin or cortisol that enter the bloodstream, targeting distant organs to regulate processes like metabolism. Unlike exocrine glands (e.g., sweat, sebaceous) using ducts, or neurons releasing neurotransmitters into synapses, endocrine glands' blood-mediated delivery defines them. Sebaceous and sweat glands are exocrine, not endocrine. This circulatory transport distinguishes endocrine function, critical for systemic coordination, contrasting with localized synaptic or ductal mechanisms.
