Anterior pituitary cascading physiological responses. Hormone secretion from the anterior pituitary gland is regulated by hormones secreted by the hypothalamus. Neuroendocrine cells in the hypothalamus project axons to the median eminence, at the base of the brain. At this site, these cells can release substances into small blood vessels that travel directly to the anterior pituitary gland (the hypothalamo-hypophyseal portal vessels). Aside from hypothalamic control of the anterior pituitary, other systems in the body have been shown to regulate the anterior pituitary’s function. GABA can either stimulate or inhibit the secretion of luteinizing hormone (LH) and growth hormone (GH) and can stimulate
Pituitary gland referred to the pituitary gland by only using the (Ancient Greek) name ἀδήν, "gland". He described the pituitary gland as part of a series of secretory organs for the excretion of nasal mucus. Anatomist Andreas Vesalius translated ἀδήν with "glans, in quam pituita destillat", "gland in which slime ("pituita") drips". Besides this 'descriptive' name, Vesalius used "glandula pituitaria", from which the English name "pituitary gland" is ultimately derived. The expression "glandula pituitaria" is still used as official synonym beside "hypophysis" in the official Latin nomenclature "Terminologia Anatomica". In the seventeenth century the supposed function of the pituitary gland to produce
