The lower end of the ala cinerea is crossed by a narrow translucent ridge, the funiculus separans, and between this funiculus and the clava , is a small tongue-shaped area, the area postrema .
The Area postrema, one of the circumventricular organs , detects toxins in the blood and acts as a vomit inducing center. It connects to the Nucleus of the Solitary Tract and other autonomic control centers in the brainstem.
