Elaborate Dissection of Cadaveric Head. The frontal, sphenoid, temporal, and occipital bones have been extensively dissected to permit visualization of the cerebrovascular and cranial nerve structures. The tentorium has been removed on the left to permit visualization of the supracerebellar space. Remnants of the cerebral falx and tentorium remain to outline the dural boundaries within the cranial space. The lateral orbital wall has been removed in order to demonstrate the lacrimal gland and globe. (Image courtesy of M Nunez)
