| anterior hypothalamic region | The rostral portion of the hypothalamus that includes preoptic, supraoptic, paraventricular and anterior hypothalamic nuclei; the hypothalamic structures located internally in the general area of the optic chiasm. (05 Mar 2000) |
|---|---|
| ventromedial hypothalamic nucleus | <anatomy> A nucleus of the middle hypothalamus, the largest cell group of the tuberal region with small-to-medium size cells. (12 Dec 1998) |
| paraventricular hypothalamic nucleus | Nucleus in the anterior part of the hypothalamus. (12 Dec 1998) |
| posterior hypothalamic area | Caudal portions of the hypothalamus located internally in the area of the mamillary body, includes medial, intermediate, and lateral mamillary nuclei and the posterior hypothalamic nuclei. Synonym: posterior hypothalamic area. (05 Mar 2000) |
| posterior hypothalamic nucleus | A large, periventricular hypothalamic nucleus located dorsal to the mamillary body, continuous with the central gray substance of the mesencephalon. Synonym: nucleus posterior hypothalami. (05 Mar 2000) |
| posterior hypothalamic region | Caudal portions of the hypothalamus located internally in the area of the mamillary body, includes medial, intermediate, and lateral mamillary nuclei and the posterior hypothalamic nuclei. Synonym: posterior hypothalamic area. (05 Mar 2000) |
| hypothalamic | Of or involving the hypothalamus. (18 Nov 1997) |
| hypothalamic amenorrhoea | Secondary amenorrhoea arising from defective hypothalamic stimulation of the anterior lobe of the hypophysis. (05 Mar 2000) |
| hypothalamic area, anterior | Loose heterogeneous collection of cells in the anterior hypothalamus, continuous rostrally with the medial and lateral preoptic areas and caudally with the tuber cinereum. (12 Dec 1998) |
| hypothalamic area, lateral | An area in the middle hypothalamus continuous rostrally with the lateral preoptic area and caudally with the tegmentum mesencephali. It contains the tuberomammillary and lateral tuberal nuclei. (12 Dec 1998) |
| hypothalamic histiocytoma | <radiology> Parasellar tumour, may not be able to differentiate from: suprasellar (optic nerve/chiasm) glioma, teratoma, kids with tumour usually have, diabetes insipidus, skeletal lesions of histiocytosis (12 Dec 1998) |
| hypothalamic hormones | Hormones isolated from the hypothalamus which exercise control over other organs, primarily the pituitary gland. Well-known members include certain pituitary hormone-releasing hormones and pituitary hormone release inhibiting hormones. Vasopressin and oxytocin which are found in the posterior pituitary may also be secreted by the hypothalamus but are not grouped here (pituitary hormones, posterior). (12 Dec 1998) |
| hypothalamic infundibulum | The apical portion of the tuber cinereum extending into the stalk of the hypophysis. Synonym: infundibulum hypothalami. (05 Mar 2000) |
| hypothalamic neoplasms | Neoplasms located in the hypothalamus including the anterior, medial, and posterior portions. (12 Dec 1998) |
| 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.
