| hypothalamic obesity with hypogonadism | A disorder characterised primarily by obesity and hypogonadotrophic hypogonadism in adolescent boys; dwarfism is rare, and when present is thought to reflect hypothyroidism. Visual loss, behavioural abnormalities, and diabetes insipidus may occur. Frohlich's syndrome often is used synonymously for this disorder, although the original case involved a pituitary tumour; most cases are thought to result from hypothalamic dysfunction in areas regulating appetite and gonadal development. The most common causes are pituitary and hypothalamic neoplasms. Synonym: adiposis orchica, adiposogenital degeneration, adiposogenital dystrophy, adiposogenital syndrome, hypophysial syndrome, hypothalamic obesity with hypogonadism. Origin: L. Fr. G. Dys-, bad, + trophe, nourishment (05 Mar 2000) |

| hypothalamic sulcus | A groove in the lateral wall of the third ventricle on either side leading from the interventricular foramen to the aditus ad aqueductum cerebri; the sulcus-demarcated boundary between dorsal thalamus and hypothalamus. Synonym: sulcus hypothalamicus, Monro's sulcus. (05 Mar 2000) |
| dorsal hypothalamic region | The portion of the hypothalamus located immediately ventral to the hypothalamic sulcus; contains small nuclei, some of which are associated with the ansa lenticularis and the entopeduncular nucleus. (05 Mar 2000) |
| dorsomedial hypothalamic nucleus | An aggregation of cells in the middle hypothalamus dorsal to the ventromedial nucleus and bordering the third ventricle. (12 Dec 1998) |
| intermediate hypothalamic region | The infundibular portion of the hypothalamus, includes the medial tuberal nuclei and portions of the dorsomedial, ventromedial, arcuate (infundibular), posterior and lateral hypothalamic nuclei; located internally in the general area of the infundibulum. (05 Mar 2000) |
| lateral hypothalamic area | Extends throughout most of the rostrocaudal extent of the hypothalamus lateral to the column of the fornix; includes lateral tuberal nuclei, tuberomamillary nuclei, and diffuse populations of cells. Synonym: lateral hypothalamic area. (05 Mar 2000) |

| adrenocortical hormones | Hormone's secreted by the human adrenal cortex; e.g., cortisol, aldosterone, corticosterone. (05 Mar 2000) |
| adrenomedullary hormones | Hormones produced by the adrenal medulla, particularly the catecholamines epinephrine and norepinephrine. (05 Mar 2000) |
| pancreatic hormones | Peptide hormones secreted into the blood by cells in the islets of langerhans of the pancreas. The alpha cells secrete glucagon; the beta cells secrete insulin; the delta cells secrete somatostatin; and the pp cells secrete pancreatic polypeptide. (12 Dec 1998) |
| gastrointestinal hormones | Hormones that originate in and regulate motor and secretory activity of the digestive organs. (12 Dec 1998) |
| parathyroid hormones | Polypeptide hormones (84 amino acid residues) secreted by the parathyroid glands, which promote release of calcium from bone to extracellular fluid by activating osteoblasts and inhibiting osteoclasts, indirectly promote increased intestinal absorption of calcium, and promote renal tubular reabsorption of calcium and increased renal excretion of phosphates. It is a major regulator of bone metabolism. Secretion of parathyroid hormone increases when the level of calcium in the extracellular fluid is low. Its action is opposed by calcitonin. (12 Dec 1998) |
| vertebrate hormones | Hormones synthesised in vertebrates. (05 Mar 2000) |
| glycoprotein hormones, alpha subunit | A non-covalently bound subunit of the glycoprotein hormones tsh, fsh, lh, and hcg which originates in the anterior pituitary gland and placenta. This subunit is virtually identical in structure and indistinguishable by radioimmunoassay in all of the above glycoproteins. It is present in both men and women, but is elevated in postmenopausal women and in patients with hypothyroidism, uraemia and malignant tumours. The alpha subunit may be involved directly in recognition of certain receptors. (12 Dec 1998) |
| gonadal hormones | Hormones having oestrogenic (female sex hormones) or androgenic (male sex hormones) activity. (12 Dec 1998) |
