In the heart when atrial muscle is. Atrial natriuretic peptide (ANP) is a cardiac hormone known to mediate increased capillary permeability, vasodilation, and natriuresis. Since specific receptors for ANP exist in both the eye and brain, possibly playing a role in ocular and cerebrospinal fluid regulation, we postulated that ANP might also be involved in inner ear fluid by: Participation of G Proteins in Natriuretic Peptide Hormone Secretion from Heart Atria Article (PDF Available) in Endocrinology (11) December with 36 Reads How we measure 'reads'.

The heart atria represent the major site of synthesis for atrial natriuretic peptide (ANP) which exerts potent natriuretic, diuretic and vasoactive functions. Recently, ANP-immunoreactivity has been detected in extracardial organs involved in water and electrolyte homeostasis, such Cited by: Atrial natriuretic peptide or atrial natriuretic factor (ANF) is a hormone secreted from cells in the right atrium of the heart when right atrial pressure increases.

The release of this cardiac peptide is stimulated by increases in the stretch of the atrial wall caused by an increase in blood pressure or blood volume. ANF receptors are also. Atrial natriuretic peptide (ANP) is a amino acid peptide that is synthesized, stored, and released by atrial myocytes in response to atrial distension, angiotensin II stimulation, endothelin, and sympathetic stimulation (beta-adrenoceptor mediated).

Therefore, elevated levels of ANP are found during hypervolemic states. Atrial Natriuretic Peptide (ANP) is a peptide hormone released by cardiomyocytes primarily in the right and left atria of the heart. Release of ANP is stimulated by over-stretching of the atria and thus occurs in contexts of cardiac over-filling.
