The major stimuli for AVP secretion are hyperosmolality and effective circulating volume depletion, which are sensed by osmoreceptors and baroreceptors, respectively. Osmoreceptors are specialized cells in the hypothalamus that perceive changes in the extracellular fluid (ECF) osmolality.
Where does antidiuretic hormone come from?
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.
What stimulates ADH secretion quizlet?
1. Osmoreceptors (specialized neurons of hypothalamus monitor changes in intercellular osmolality (relative concentrations of electrolytes and water). If the concentration of electrolytes increases or if the concentration of water decreases, then ADH secretion is stimulated.
