WebEndocrinology is the study of the endocrine system (i.e., the hypothalamus, pituitary gland, thyroid gland, adrenals, and gonads), metabolic diseases, and certain aspects of nutritional medicine.The endocrine glands are responsible for producing and secreting hormones, which influence the function of cells in certain tissues of the body. Hormone secretion is … WebPulsatile GnRH secretion stimulates the pituitary gland to secrete luteinizing hormone (LH) and follicle stimulating hormone (FSH). The pituitary gland translates the tempo set by the hypothalamus into a signal, LH and FSH secretion, that can be understood by the ovarian follicle. The ovarian follicle is composed of three key cells: theca cells ...
GnRH is secreted in the hypophysial portal bloodstream at the median eminence. The portal blood carries the GnRH to the pituitary gland, which contains the gonadotrope cells, where GnRH activates its own receptor, gonadotropin-releasing hormone receptor (GnRHR), a seven-transmembrane G-protein-coupled receptor that stimulates the beta isoform of Phosphoinositide phospholipase C, which goes on to mobilize calcium and protein kinase C. This results in the acti…
