Lateral aperture

Lateral aperture
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, which end in the foramen of Luschka.

The lateral aperture is a paired structure in human anatomy. It is an opening in each lateral extremity of the lateral recess of the fourth ventricle of the human brain, which also has a single median aperture. The two lateral apertures provide a conduit for cerebrospinal fluid to flow from the brain's ventricular system into the subarachnoid space; specifically into the pontocerebellar cistern at the cerebellopontine angle. The structure is also called the lateral aperture of the fourth ventricle or the foramen of Luschka after anatomist Hubert von Luschka.^[1]
