Abstract

The lamina terminalis, which forms most of the anterior wall of the third ventricle, consists of the median preoptic nucleus and two circumventricular organs (CVOs), the subfornical organ and organum vasculosum of the lamina terminalis. These latter two regions lack a blood-brain barrier and, unlike other regions of the brain, are influenced by the hormonal and ionic composition of the blood. The CVOs of the lamina terminalis are rich in receptors for a number of circulating peptides and the subfornical organ and the OVLT are clearly established as the prime cerebral targets for circulating angiotensin II, atrial natriuretic peptide (AVP) and relaxin to influence central nervous system pathw..
