The gravitational constant, approximately 6989667400000000000â 6.674Ã10â11 Nâm2/kg2 and denoted by letter G, is an empirical physical constant involved in the calculation(s) of gravitational force between two bodies.
Diabetes insipidus is caused by a lack of antidiuretic hormone (ADH), also called vasopressin, which prevents dehydration, or the kidney's inability to respond to ADH. ADH enables the kidneys to retain water in the body. The hormone is produced in a region of the brain called the hypothalamus. It is stored and released from the pituitary gland, a small gland at the base of the brain. When diabetes insipidus is caused by a lack of ADH, it is called central diabetes insipidus.
ACTH. n. Adrenocorticotropic hormone; a hormone that is produced by the anterior lobe of the pituitary gland and that stimulates the secretion of cortisone, aldosterone, and other hormones by the adrenal cortex.Also called adrenocorticotropin, adrenotropin, corticotropin.CTH. adrenocorticotropic hormone; produced by the anterior lobe of the pituitary gland that stimulates the cortex of the adrenal gland to secrete its hormones, including corticosterone. If production of ACTH falls below normal, the adrenal cortex decreases in size, and production of the cortical hormones declines.
