| 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 dwarfism | Short stature due to underpreformance of the pituitary gland (specifically of the anterior pituitary). (12 Dec 1998) |
| 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 infantilism | Short stature due to underpreformance of the pituitary gland (specifically of the anterior pituitary). (12 Dec 1998) |
| pituitary membrane | The mucous membrane lining the nasal cavity. (12 Dec 1998) |
| pituitary myxoedema | Myxoedema resulting from inadequate secretion of the thyrotropic hormone; commonly occurs in association with inadequate secretion of other anterior pituitary hormones. (05 Mar 2000) |
| pituitary stalk section | Transection of the neurovascular connection between the hypothalamus and the pituitary gland. (05 Mar 2000) |
