The lamina terminalis forms the anterior wall of the third ventricle and anterior boundary of the hypothalamus.
Gross anatomy
It is a thin membrane that stretches between the dorsal surface of the optic chiasm to the anterior commissure 1. Anterior to the lamina terminalis is the lamina terminalis cistern, which contains the anterior cerebral artery and anterior communicating artery complex. It contains one of the seven circumventricular organs (CNS), the vascular organ of the lamina terminalis.
Development
It is formed from the rostral end of the neural tube. Early in development, crossing fibers from each cerebral ventricle form together in the lamina terminalis to create the anterior commissure.
