Vascular organ of lamina terminalis
(Redirected from Organum vasculosum of lamina terminalis)
The Vascular Organ of Lamina Terminalis (VOLT) is a specialized structure located in the brain, specifically in the anterior wall of the third ventricle. It is part of the circumventricular organs (CVOs), a group of structures in the brain characterized by their extensive vasculature and lack of a blood-brain barrier.
Anatomy[edit | edit source]
The VOLT is situated in the lamina terminalis, a thin membrane that stretches from the optic chiasm to the anterior commissure. It is one of the smallest CVOs, but despite its size, it plays a crucial role in the body's homeostatic mechanisms.
Function[edit | edit source]
The VOLT is involved in several physiological processes, including the regulation of body temperature, thirst, and water balance. It is also believed to play a role in cardiovascular regulation. The VOLT's lack of a blood-brain barrier allows it to monitor changes in the composition of the blood and respond accordingly.
Clinical Significance[edit | edit source]
Due to its location and functions, the VOLT is implicated in several pathological conditions. These include dehydration, hypertension, and certain neurological disorders. Further research is needed to fully understand the VOLT's role in these conditions.
