| receptors, pituitary hormone-regulating hormone | Cell surface receptors that bind the hypothalamic hormones regulating pituitary cell differentiation, proliferation, and hormone synthesis and release, including the pituitary-releasing and release-inhibiting hormones. The pituitary hormone-regulating hormones are also released by cells other than hypothalamic neurons, and their receptors also occur on non-pituitary cells, especially brain neurons, where their role is less well understood. Receptors for dopamine, which is a prolactin release-inhibiting hormone as well as a common neurotransmitter, are not included here. (12 Dec 1998) |
|---|---|
| growth hormone inhibiting hormone | <protein> Gastrointestinal and hypothalmic peptide hormone (two forms: 14 and 28 residues), found in gastric mucosa, pancreatic islets, nerves of the gastrointestinal tract, in posterior pituitary and in the central nervous system. Inhibits gastric secretion and motility: in hypothalamus/pituitary inhibits somatotropin release. (18 Nov 1997) |
| growth hormone-regulating hormone | <endocrinology> Hypothalamic hormones that induce (somatoliberin) or inhibit (somatostatin) the release of growth hormone (somatotropin). (18 Nov 1997) |
| growth hormone-releasing hormone | <endocrinology> Peptide hormone related to the glucagon family, released from the pituitary, acts on the adenohypophysis to release growth hormone. Synonym: somatoliberin, growth hormone-releasing factor. (20 Sep 2002) |
| hormones, hormone substitutes, and hormone antagonists | A collective grouping for both naturally occurring and synthetic hormones, substitutes, and antagonists. (12 Dec 1998) |
| follicle-stimulating hormone-releasing hormone | A decapeptide of hypothalamic origin capable of accelerating pituitary secretion of follitropin. Synonym: follicle-stimulating hormone-releasing factor, follicle-stimulating hormone-releasing hormone. Origin: follicle-stimulating hormone + L. Libero, to free, + -in (05 Mar 2000) |
| luteinizing hormone/follicle-stimulating hormone-releasing factor | gonadotrophin-releasing hormone |
| luteinizing hormone-releasing hormone | A hormone that controls sex hormones in men and women. Also called lhrh. (12 Dec 1998) |
| anterior border of testis | An imaginary convex line demarcating the lateral and medial surfaces. Synonym: margo anterior testis. (05 Mar 2000) |
| appendix of the testis | A vesicular nonpedunculated structure attached to the cephalic pole of the testis; a vestige of the cephalic end of the paramesonephric (mullerian) duct. Synonym: appendix testis, appendix of the testis, nonpedunculated hydatid, ovarium masculinum, sessile hydatid. (05 Mar 2000) |
| appendix testis | A small solid projection of tissue on the outer surface of the testis which is a remnant of the embryologic mullerian duct. (12 Dec 1998) |
| blood-testis barrier | The membrane in the testis that separates sperm from the bloodstream. (09 Oct 1997) |
| vaginal process of testis | A peritoneal diverticulum in the embryonic lower anterior abdominal wall that traverses the inguinal canal; in the male it forms the tunica vaginalis testis and normally loses its connection with the peritoneal cavity; a persistent processus vaginalis in the female is known as the canal of Nuck. Synonym: Nuck's diverticulum, processus vaginalis peritonei, vaginal process of peritoneum, vaginal process of testis. (05 Mar 2000) |
| vanished testis syndrome | <syndrome> Absence of both testes in a male with normal chromosomes (XY) and otherwise normal genitalia at birth and during childhood. Testes were present in at least the first trimester of gestation, but vanished sometime thereafter. (05 Mar 2000) |
| margo anterior testis | An imaginary convex line demarcating the lateral and medial surfaces. Synonym: margo anterior testis. (05 Mar 2000) |
