What is the Meaning of Antidiuretic Hormone?

Antidiuretic Hormone (ADH), also known as arginine vasopressin, is a vital peptide hormone synthesized in the hypothalamus and released by the posterior pituitary gland. Its primary function is to regulate fluid balance, blood volume, and osmolality within the body by acting on the renal tubules. Clinically, ADH levels are crucial in diagnosing conditions like diabetes insipidus, which is characterized by the body's inability to properly conserve water. The hormone is an essential component of the body's complex system for maintaining hydration and electrolyte equilibrium.

What is the Origin of Antidiuretic Hormone?

The name antidiuretic directly reflects the hormone's core physiological action, derived from the Greek anti, meaning "against," and diuresis, meaning "increased urination." The alternative name, vasopressin, is a compound term referencing its secondary effect of vaso-constriction and its nature as a pressin or pressure-increasing substance. Its discovery and subsequent identification as a key regulator of water retention marked a significant advance in the field of renal and endocrine physiology.

What is the Mechanism of Antidiuretic Hormone?

ADH operates by binding to V2 receptors located on the principal cells of the renal collecting ducts, initiating a cascade that leads to the insertion of aquaporin-2 water channels into the apical membrane. This action dramatically increases the permeability of the collecting ducts to water, facilitating its reabsorption back into the circulation and concentrating the urine. Additionally, at higher concentrations, ADH acts on V1 receptors on vascular smooth muscle, causing vasoconstriction and thus elevating arterial blood pressure. The release of ADH is principally triggered by increased plasma osmolality detected by osmoreceptors in the hypothalamus or by a decrease in effective circulating blood volume.
