What is the function of Foramina of Luschka?

The Foramina of Luschka, also known as lateral apertures, are openings located in the fourth ventricle of the brain. Their primary function is to allow the cerebrospinal fluid (CSF) to flow from the ventricular system into the subarachnoid space, facilitating the circulation of CSF around the brain and spinal cord. This flow is essential for cushioning the brain, removing waste, and maintaining intracranial pressure.
