Hormones secreted by adenohypophysis and their functions
Explain all the hormones secreted by the adenohypophysis? Mention their respective functions?
Expert
The adenohypophisys secretes many hormones like GH (growth hormone), prolactin. Besides these hormones, it also secretes ACTH (adrenocorticotropic hormone), TSH (thyroid-stimulating hormone), FSH (follicle-stimulating hormone) and LH (luteinizing hormone). GH, also known as somatotropic hormone (STH), acts upon bones, cartilages and muscles promoting the growth of these tissues. Prolactin is the hormone which stimulates the production and secretion of milk by the mammary glands in women. The ACTH hormone stimulates the cortical portion of the adrenal gland to produce and secrete the cortical hormones (glucocorticoids). The TSH hormone stimulates the activity of the thyroid gland increasing the production and secretion of its hormones T3 and T4. The FSH is gonadotropic hormone, means it stimulates the gonads and in women, it acts on the ovaries inducing the growth of follicles, in men its work is to stimulate spermatogenesis. The LH hormone is also a gonadotropic hormone that acts upon the ovaries of women to stimulate ovulation and the formation of the corpus luteum (that secretes estrogen) and in men upon the testicles and stimulates the production of testosterone harmone.
