The epidural, subdural and subarachnoid spaces are demonstrated and discussed with respect to trauma and disease. The relationship of the brainstem and cerebellum to the tentorium demonstrates the vulnerability of the brain stem to increased supratentorial pressure and herniation. Arachnoid granulations and the sagittal sinus are shown. A subdural hematoma specimen as well as sections from a ruptured aneurysm complete the demonstration.
