Lamina terminalis
Encyclopedia
The median portion of the wall of the fore-brain vesicle consists of a thin lamina, the lamina terminalis, which stretches from the interventricular foramen to the recess at the base of the optic stalk
and contains the organum vasculosum of the lamina terminalis
, which regulates the osmolarity of the blood.
This is the rostral end (tip) of the neural tube
(embryological central nervous system
) in the early weeks of development.
Optic stalk
The optic vesicles project toward the sides of the head, and the peripheral part of each expands to form a hollow bulb, while the proximal part remains narrow and constitutes the optic stalk....

Organum vasculosum of the lamina terminalis
The organum vasculosum of the lamina terminalis is one of the circumventricular organs of the brain. Other circumventricular organs are the subfornical organ and the area postrema in the brainstem.-AV3V region:...
