Document Summary

First 2 pairs attach to the forebrain. The rest attach to the brain stem: except for cranial nerve x (vagus nerve) extends to abdomen. How to remember names: oh, oh, oh, to touch and feel very good velvet, How to remember function: some say marry money but my brother says big. Cranial nerves contain the sensory and motor nerve fibers that innervate the head. Cell bodies of the sensory neurons lie either in receptor organs or within cranial sensory ganglia, which lie along some cranial nerves. Cell bodies of most cranial motor neurons occur in cranial nerve nuclei in the ventral gray matter of the brain stem. Primarily or exclusively sensory nerves: cn1, 2 and 8: contain special sensory fibers for smell (1), vision (2), and hearing and equilibrium (8) Primarily motor nerves: cn 3, 4, 6, 11, 12: contain somatic motor fibers to skeletal muscles of the eye, neck and tongue.
