What are the foramina of Luschka commonly referred to as?

The foramina of Luschka are commonly referred to as lateral apertures. These openings are located at the lateral aspect of the fourth ventricle in the brain and allow for the flow of cerebrospinal fluid (CSF) from the ventricles into the subarachnoid space surrounding the brain. This is an essential part of the circulatory system of CSF, which provides cushioning, removes waste, and facilitates chemical stability. Their positioning as lateral apertures distinguishes them from the median aperture (located at the midline) and is key for understanding the anatomy and physiology of the cerebral ventricular system. The effective drainage of CSF through these foramina into the surrounding space is crucial for maintaining intracranial pressure and overall brain health.
