There are twelve cranial nerves which originate in the brainstem, which are identified by Roman numerals (as well as a common mane)  in order as they arise from progressively lower portions of the brainstem or forebrain.  The functions are varied, and include control of movement or the eyes, hearing, sensation, smell, sight, mucous membrane function, and control of bowel, heart and lung functions.
