NEET PG DENTAL EXAM

Detailed explanation-1: -Antidiuretic hormone (ADH) is a chemical produced in the brain that causes the kidneys to release less water, decreasing the amount of urine produced. A high ADH level causes the body to produce less urine. A low level results in greater urine production.

Detailed explanation-2: -ADH is the primary hormone responsible for tonicity homeostasis. Hyperosmolar states most strongly trigger its release. ADH is stored in neurons within the hypothalamus. These neurons express osmoreceptors that are exquisitely responsive to blood osmolarity and respond to changes as little as two mOsm/L.

Detailed explanation-3: -Pathophysiology. Antidiuretic hormone (ADH) induces water retention by increasing the permeability of nephrons. Its influence on water permeability occurs primarily by regulating aquaporin 2 water channels in the distal tubules and collecting ducts of the kidney (Kwon et al., 2001).
