Question

Hypothalamus directly controls the production of which of the following hormones?

• A. Glucocorticoid and insulin
• B. Insulin and glucagon
• C. Atrial natriuretic factor and gastrin
• D. Glucocorticoids and androgens

Answer 1

The correct option is D Glucocorticoids and androgens

Hypothalamus plays very important role in maintaining body temperature and heart rate. It is also important to maintain homeostasis. Various hormones are produced and released by hypothalamus. It produces releasing and inhibiting hormones which in turn release or inhibit the production of pituitary hormones. The hormones produces are Anti-diuretic hormone (ADH), Corticotropin-releasing hormone (CRH), Gonadotropin-releasing hormone (GnRH), somatostain, oxytocin, Dopamine. During stress, CRH stimulates the production of ACTH from the pituitary gland. This in turn secretes glucocorticoids. Glucocorticoids increase blood glucose levels. GnRH stimulates the production and release of follicle-stimulating hormone (FSH) and luteinizing hormone (LH) from pituitary gland. This in turn increases production of androgen from testes.

Thus, the correct answer is option D.
