Question

What are the tropic hormones of anterior pituitary

Answer 1

The tropic hormones or trophic hormones are the hormonal mechanism by which the two main glands, hypothalamus and anterior pituitary or adenohypophysis, stimulate the secretion of new hormones in the target tissues. The tropic action takes place by the use of trophic hormones (sometimes also called tropic hormones, by its Greek root tropes, which means "affinity for something") There are two categories of tropic or liberating hormones:  Hypophysiotropic hormones: They are secreted in the hypothalamus and regulate the secretion of hormones from the anterior pituitary gland. They are also called hypophysiotropic factors, and they are hormones of peptide nature. An example is growth hormone-releasing hormone (GHRH)Liberating hormones anterior pituitary: They are secreted in the anterior pituitary and regulate the secretion of hormones in other tissues. Examples are thyroid stimulating hormone (TSH) and adrenocorticotropic hormone (ACTH). The tropic hormones that affect numerous processes are called pleiotropic.  "Creative Commons License Attribution Share Equal 3.0 (Wikimedia Foundation, Inc.)"
The adenohypophysis is often referred to as the "master gland," that is, the hypothalamus, which organizes the complex regulatory function of many other endocrine glands. The anterior pituitary produces six important hormones: 1) prolactin (PRL, prolactin), 2) growth hormone (GH, growth hormone), 3) adrenocorticotropic hormone (ACTH, adrenocorticotropic hormone), 4) luteinizing hormone (LH, luteinizing hormone) , 5) follicle-stimulating hormone (FSH, follicle-stimulating hormone) and 6) thyroid stimulating hormone (TSH, thyroid-stimulating hormone) (Table 401e-1). The secretion of pituitary hormones is pulsatile and reflects the stimulus exerted by a set of specific hypothalamic releasing factors. Each of these pituitary hormones elicits specific responses in other peripheral glandular tissues. In turn, the hormones produced by these peripheral glands regulate the function of the pituitary gland by feedback at the level of the hypothalamus and the pituitary gland itself. "(Shlomo Melmed, J.
