NEET PG DENTAL EXAM

Detailed explanation-1: -Antidiuretic hormone is made by a part of the brain called the hypothalamus and is secreted into the blood by the pituitary gland. Certain types of tumors may release high amounts of antidiuretic hormone, which can cause low levels of sodium in the blood and the body to retain water.

Detailed explanation-2: -Anti-diuretic hormone is made by special nerve cells found in an area at the base of the brain known as the hypothalamus. The nerve cells transport the hormone down their nerve fibres (axons) to the posterior pituitary gland where the hormone is released into the bloodstream.

Detailed explanation-3: -ADH is a 9 amino acid peptide synthesized in cells in the supraoptic nucleus and paraventricular nucleus in the hypothalamus. It travels down the axons of these cells and is secreted in the posterior pituitary in response to hypovolemia and to plasma hyperosmolarity.

Detailed explanation-4: -The ADH is activated by the posterior portion of the pituitary gland. The anti-diuretic hormone is secreted by the neurohypophysis of the pituitary gland. Since it stimulates the constriction of blood vessels and results in an increase in blood pressure, therefore it is called vasopressin.
