| hypophysial fossa | Fossa of the sphenoid bone housing the pituitary gland. See: sella turcica. Synonym: fossa hypophysialis, pituitary fossa. (05 Mar 2000) |
| hypophysial infantilism | Growth hormone deficiency due to failure of hypothalamic growth hormone-releasing hormone (also known as somatocrinin.) (05 Mar 2000) |
| hypophysial portal circulation | A capillary network that carries hypophyseotropic hormones from the hypothalamus, where they are secreted into blood, to their sites of action in the anterior hypophysis. See: portal circulation, hypophysis, hypothalamus. Synonym: hypophyseoportal system, hypophysial portal circulation, hypophysial portal system, hypophysioportal system, hypothalamohypophysial portal circulation, hypothalamohypophysial portal system. (05 Mar 2000) |
| hypophysial portal system | A capillary network that carries hypophyseotropic hormones from the hypothalamus, where they are secreted into blood, to their sites of action in the anterior hypophysis. See: portal circulation, hypophysis, hypothalamus. Synonym: hypophyseoportal system, hypophysial portal circulation, hypophysial portal system, hypophysioportal system, hypothalamohypophysial portal circulation, hypothalamohypophysial portal system.

| hypophysial syndrome | 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) |
| hypophysin | An aqueous extract of the posterior lobe of the fresh hypophysis of cattle; contains oxytocin and vasopressin. (05 Mar 2000) |
| hypophysio-sphenoidal syndrome | <syndrome> Neoplastic invasion of the base of the skull in the region of the sphenoidal sinus, often with destruction of the dorsum sellae. (05 Mar 2000) |
| hypophysioportal system | A capillary network that carries hypophyseotropic hormones from the hypothalamus, where they are secreted into blood, to their sites of action in the anterior hypophysis. See: portal circulation, hypophysis, hypothalamus. Synonym: hypophyseoportal system, hypophysial portal circulation, hypophysial portal system, hypophysioportal system, hypothalamohypophysial portal circulation, hypothalamohypophysial portal system. (05 Mar 2000) |
| hypophysioprivic | Denoting the condition in which the pituitary gland may be functionally inactive or may be absent, as after hypophysectomy. Synonym: hypophyseoprivic. Origin: hypophysis + L. Privus, deprived of (05 Mar 2000) |
| hypophysiotropic | Denoting a stimulatory hormone that acts on the pituitary gland (hypophysis). Synonym: hypophyseotropic. (05 Mar 2000) |
| hypophysiotropic hormone | A hormone that stimulates the rate of secretion of hypophysial hormone's; e.g., a releasing factor. (05 Mar 2000) |
| hypophysis | 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) |
| hypophysis cerebri | pituitary gland |
| hypophysis sicca | The cleaned, dried, and powdered posterior lobe obtained from the pituitary body of domestic animals used for food by humans; an oxytocic, vasoconstrictor, antidiuretic, and a stimulant of intestinal motility. Synonym: desiccated pituitary, hypophysis sicca. (05 Mar 2000) |

| hypothermia |
A fall in the temperature of an animal body below the usual level. This state is brought about when the homeostatic mechanisms fail to maintain adequate production of heat under conditions of extreme cold.

| hypochlorous acid |
A weak, unstable acid, formula HOCl. Hypochlorous acid is also a minor component of the gas-phase inorganic chlorine budget in the stratosphere. It is formed there largely from reaction of hydroperoxyl radicals (HO 2 ) with chlorine monoxide (ClO) radicals, and from the hydrolysis of chlorine nitrate on stratospheric aerosols. It is subject to quite rapid photolysis in the sunlit atmosphere.
