Presents neurosurgical anatomy by detailing approaches on cadavers in the same position patients would be placed in during a real operative procedure. Anatomy is described in: 1) all commonly used cranial and cranial base approaches, 2) anterior, posterior, anterolateral and posterolateral approaches to all segments of the spine, 3) all commonly performed procedures on peripheral nerves, and 4) endoscopic approaches to cranial and spinal neurosurgery. Stresses the understanding of the anatomy rather than the performance of the procedure.
