Borders of the Fourth ventricle, Rhomboid Fossa
The 4th ventricle is the ventricular component of the pons and medulla. Location: between the cerebellum and the pons and medulla. Connections: Superiorly - connects to the cerebral aqueduct in the midbrain. Inferiorly - connects to the central canal in the spinal cord. Laterally - has 2 openings, 1 on each side, - Foramen of Luschka . Also called the lateral aperture. Connect the 4th ventricle to the part of the subarachnoid space called the cistern of the great cerebral vein(Superior cistern, Quadrigeminal cistern) Lateral recess - The area in the ventricle adjacent to the foramen of Luschka. Posteriorly - 1 opening - Foramen of Magendie. Also called the median aperture. Connect the 4th ventricle to the part of the subarachnoid space called cisterna magna(also called Cisterna cerebellomedullaris). As all ventricular spaces, the 4th ventricle has an ependymal cell layer. Ependymal cells are a specialized type of epithelial cells that line the ventricular system ...
