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.
