The arcuate nucleus of the hypothalamus (also known as ARH, ARC, or infundibular nucleus ) is an aggregation of neurons in the mediobasal hypothalamus, adjacent to the third ventricle and the median eminence. The arcuate nucleus includes several important and diverse populations of neurons that help mediate different neuroendocrine and physiological functions, includi… WebJan 9, 2024 · Control of the reproductive axis originates in the hypothalamus with the periodic pulsatile release of gonadotropin-releasing hormone (GnRH). In response to GnRH (also called luteinizing hormone-releasing hormone or LHRH), the pituitary releases pulses of the gonadotropins, luteinizing hormone (LH) and follicle-stimulating hormone (FSH), …
WebThis occurs through the production and release of GnRH from GnRH neurons in the medial pre-optic area and the arcuate nucleus of the hypothalamus (Feingold et al., 2000). GnRH is then secreted into the hypophyseal portal vascular system which carries GnRH to anterior pituitary gonadotrope cells. WebGonadotropin-releasing hormone (GnRH) is the central neuroendocrine regulator of the hypothalamic-pituitary-gonadal axis. Luteinizing Hormones (LH) and Follicle Stimulating Hormones (FSH) are the two gonadotropic hormones that are secreted by the gonadotropic cells in the pituitary gland and are stimulated by the gonadotropin releasing hormones.
