Three-dimensional representation of the ventricular system of the human brain. The fourth ventricle is the lower blue mass. The little points sticking out on the left and right are the two parts of the lateral recess.
The lateral recess is a projection of the fourth ventricle which extends into the inferior cerebellar peduncle of the brainstem. The lateral aperture, an opening in each extremity of the lateral recess, provides a conduit for cerebrospinal fluid to flow from the brain's ventricular system into the subarachnoid space.
