ventricular system ( small arrows ) and enters the subarachnoid space via the medial foramen of Magendie and the two lateral foramina of Luschka. In the normal healthy person, the arachnoid is attached to the inner surface of the dura. There is no actual or potential subdural space. Creation of this subdural space results from a traumatic, infec tious, or pathologic process.

4-1 Semi-diagrammatic representation of the central nervous sys tem and its associated meninges. The details show the rela tionships of the meninges in the area of the superior sagittal sinus, on the lateral aspect of the cerebral hemisphere, and around the spinal cord. Cerebrospinal fluid is produced by the choroid plexuses of the lateral, third, and fourth ventricles. It circulates through the
