Assertion: LH and FSH stimulate gonadal activity and hence are called gonadotrophins.

Reason:  ACTH stimulates the synthesis and secretion of steroid hormones called glucocorticoids from the adrenal cortex.

Both assertion and reason are true but the reason is not the correct explanation of the assertion.

The correct answer is Option (2)- Both assertion and reason are true but the reason is not the correct explanation of the assertion.

The pituitary gland is located in a bony cavity called sella tursica and is attached to hypothalamus by a stalk . It is divided anatomically into an adenohypophysis and a neurohypophysis. Adenohypophysis consists of two portions, pars distalis and pars intermedia. The pars distalis region of pituitary, commonly called anterior pituitary, produces growth hormone (GH), prolactin (PRL), thyroid stimulating hormone (TSH), adrenocorticotrophic hormone (ACTH), luteinizing hormone (LH) and follicle stimulating hormone (FSH). ACTH stimulates the synthesis and secretion of steroid hormones called glucocorticoids from the adrenal cortex. LH and FSH stimulate gonadal activity and hence are called gonadotrophins. In males, LH stimulates the synthesis and secretion of hormones called androgens from testis. In males, FSH and androgens regulate spermatogenesis.
