1) Review the anatomy of the upper six cranial nerves. 2) Learn the functions of these cranial nerves. 3) Be able to identify common pathologies affecting these nerves.
Cranial nerve dysfunction is a common presenting symptom in many patients. In order to evaluate for a causative lesion, one must have a thorough knowlegde of the anatomy of each nerve. The anatomy of cranial nerves I-VI is presented along with a review of the function(s) of each nerve. For cranial nerves III-VI, the entire course of each nerve from brainstem exit to innervated muscles (for III, IV, V1, and VI) is reviewed. Pathology affecting these nerves is divided into brainstem, cisternal, base of skull (Meckle cave/cavernous sinus), and distal lesions. Common pathogies that affect each nerve along the various segments are presented.
