| hPFSH, HPFSH | human pituitary follicle-stimulating hormone |
| pituitary diverticulum | A tubular outgrowth of ectoderm from the stomodeum of the embryo; it grows dorsad toward the infundibular process of the diencephalon, around which it forms a cup-like mass, giving rise to the pars distalis and pars juxtaneuralis of the hypophysis. Synonym: craniopharyngeal canal, hypophyseal pouch, Rathke's diverticulum, Rathke's pocket, Rathke's pouch. (05 Mar 2000) |
|---|---|
| pituitary dwarf | Dwarfism as result of failure of growth hormone production because of hypothalamic or pituitary abnormality. Synonym: pituitary dwarf. (05 Mar 2000) |
| pituitary fossa | Fossa of the sphenoid bone housing the pituitary gland. See: sella turcica. Synonym: fossa hypophysialis, pituitary fossa. (05 Mar 2000) |
| pituitary gigantism | Excessive growth due to overactivity of the pituitary gland (specifically of the anterior pituitary). (12 Dec 1998) |
| pituitary gland | A small oval shaped endocrine gland situated at the base of the brain in the fossa (depression) of the sphenoid bone. The overall role is to regulate growth and metabolism. The gland is divided into the posterior and anterior pituitary, each responsible for the production of its own unique hormones. (27 Sep 1997) |
| pituitary gland, anterior | The glandular or anterior lobe of the pituitary gland. (12 Dec 1998) |
| pituitary gland, posterior | The neural or post-neural lobe of the pituitary gland. (12 Dec 1998) |
| pituitary gonadotropic hormone | Any gonadotropin of hypophysial origin; formerly used to designate a single hormone, because it was thought that the anterior hypophysis secreted only one gonadotropin. Synonym: pituitary gonadotropic hormone. (05 Mar 2000) |
| pituitary gonadotropins | gonadoprophins |
| pituitary growth hormone | <protein> Hormone (191 amino acids) released by anterior pituitary that stimulates release of somatomedin, thereby causing growth. (18 Nov 1997) |
| pituitary hormone release inhibiting hormones | Polypeptide hormones produced in the hypothalamus which inhibit the release of pituitary hormones. (12 Dec 1998) |
| pituitary hormone-releasing hormones | Hormones released by one structure (e.g., the hypothalamus or the thyroid gland) that effect the secretion of hormones from the pituitary gland. (12 Dec 1998) |
| pituitary hormones | Hormones secreted by the anterior and posterior lobes of the pituitary gland and the pars intermedia, an ill-defined region between the two. Their secretion is regulated by the hypothalamus. (12 Dec 1998) |
| pituitary hormones, anterior | Protein, glycoprotein, or polypeptide hormones secreted by the anterior lobe of the pituitary gland. (12 Dec 1998) |
| pituitary hormones, posterior | Hormones released from the posterior lobe of the pituitary, including vasopressin (antidiuretic hormone) and oxytocin. They are formed in the neuronal cells of the hypothalamic nuclei and stored in nerve cell endings in the posterior pituitary (neurohypophysis). (12 Dec 1998) |
