GENERAL HISTOLOGY

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: -ADH is a substance produced naturally in an area of the brain called the hypothalamus. It is then released by the pituitary gland at the base of the brain.

Detailed explanation-3: -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-4: -An increase in osmolarity of the blood is a trigger prompting the hypothalamus to release ADH, which signals cells in the kidney tubules to reabsorb more water by inserting aquaporins, thus preventing additional fluid loss in the urine.

Detailed explanation-5: -ADH, or vasopressin, is synthesized in the hypothalamus. The hormone is transported down axons in vesicles to the posterior pituitary where the hormones are stored. Secretion of ADH is highly sensitive to water balance. Once secreted, ADH causes water retention in the kidneys.
