Questions on the Endocrine System Questions
Question 1 of 5
What is the hormone produced by adipose tissue which signals satiety?
Correct Answer: B
Rationale: Leptin, from adipose tissue, signals satiety to hypothalamus, reducing hunger adiposity feedback. Melatonin (pineal) governs sleep, not eating. Thymosins (thymus) boost immunity, unrelated. Glucagon (pancreas) raises glucose, not satiety. Leptin's appetite control distinguishes it, key to energy balance, unlike sleep, immune, or glucose hormones.
Question 2 of 5
Effects of hypothyroidism include all but this
Correct Answer: A
Rationale: Hypothyroidism (low thyroid hormone) slows metabolism, causing lethargy, weight gain, and anorexia (appetite loss) not diarrhoea, which aligns with hyperthyroidism's increased motility. This exclusion distinguishes hypothyroidism's sluggish profile, critical for diagnosing thyroid disorders. Misattributing diarrhoea to hypothyroidism conflates opposing thyroid states, a key NEET differentiation for endocrine pathology.
Question 3 of 5
The endocrine gland that is formed from two different germ layers is the:
Correct Answer: C
Rationale: The pituitary forms from two germ layers: adenohypophysis from ectodermal oral epithelium (Rathke's pouch) and neurohypophysis from neural ectoderm (brain floor), integrating glandular and neural functions. Ovary and testis (gonads) derive from mesoderm and endoderm (germinal epithelium), not dual-layered uniquely. Thyroid arises from endoderm (pharyngeal floor), a single layer. Pituitary's dual origin enables diverse hormone production/storage, distinguishing it, critical for its hypothalamic-pituitary axis role.
Question 4 of 5
Which of the following is not a pituitary hormone?
Correct Answer: D
Rationale: Testosterone, an androgen from testes, isn't a pituitary hormone LH from the anterior pituitary stimulates its production. Growth hormone, luteinizing hormone, and prolactin are anterior pituitary secretions, regulating growth, reproduction, and lactation. Testosterone's gonadal origin distinguishes it, dependent on pituitary signals, unlike direct pituitary products, key to endocrine hierarchy.
Question 5 of 5
The hormone that is released from the anterior pituitary and stimulates the development of the seminiferous tubules of the testes is called:
Correct Answer: C
Rationale: Follicle-stimulating hormone (FSH) from the anterior pituitary stimulates seminiferous tubule development in testes, promoting spermatogenesis. Prolactin aids lactation, not testes. ACTH targets adrenals for cortisol. LH stimulates testosterone from Leydig cells, not tubules directly. FSH's specific role in sperm production distinguishes it, essential for male fertility, unlike other pituitary hormones' functions.
