Identify the gland that secretes cortisol and aldosterone.

Correct Answer: D

Rationale: Adrenal glands secrete cortisol (cortex, stress) and aldosterone (cortex, sodium) dual zones (fasciculata, glomerulosa). Thyroid produces T3/T4, calcitonin metabolism/calcium. Parathyroid releases PTH calcium only. Pancreas makes insulin/glucagon glucose. Adrenal's steroid output distinguishes it, key to stress and electrolyte balance, unlike metabolic or calcium glands.

Correct Answer: D

Rationale: Progesterone (ovaries) grows the uterus, preparing it for pregnancy endometrial thickening. Secondary sex characteristics (e.g., breasts) are estrogen-driven, not progesterone. Estrogen aids follicle growth, not ovum maturation directly LH triggers that. Estrogen does aid breast development false to deny. Uterine growth distinguishes progesterone, key to reproductive support, unlike characteristics, maturation, or breast errors.

Correct Answer: B

Rationale: Synaptic signaling occurs when neurons release neurotransmitters (e.g., acetylcholine) across synapses to influence adjacent neurons fast, local neural communication. Autocrine involves cells signaling themselves (e.g., growth factors). Paracrine affects nearby cells (e.g., histamine), not specifically neurons. Endocrine uses blood for distant targets (e.g., insulin), not neuron-neighbor. Synaptic specificity distinguishes it, key to nervous system function, unlike self, nearby, or systemic signaling.

Correct Answer: B

Rationale: Adrenal medulla secretes adrenaline and noradrenaline (epinephrine/norepinephrine) catecholamines for fight-or-flight. T4/T3 (thyroid) regulate metabolism, not medullary. Insulin/glucagon (pancreas) manage glucose, not adrenal. Aldosterone/cortisol (adrenal cortex) are steroids, not medulla. Adrenaline-noradrenaline's neural-endocrine role distinguishes them, critical for acute stress, unlike thyroid, pancreatic, or cortical hormones.

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.
