IMPORTANT CONSIDERATIONS: If this material is to be covered in two lectures, the obvious logical break is to address the cranial nerves in one session and the spinal nerves in the second session. If three sessions are available, the discussion of the spinal nerves can be given two sessions, with greater emphasis on functional differences among the nerves. As with most anatomical material, much of this may be best grasped by students in the laboratory where they can directly relate the diagrams of the text with three-dimensional models and specimens.
