Basic concepts

Functional components - The cranial nerves have one or more of six functional components:

  • Somatic motor (general somatic efferent (GSE)) which innervate the striate muscles of the orbit and tongue.
  • Brachial motor (special visceral efferent or (SVE)) which innervate muscles derived from the pharyngeal arches (face, larynx, and pharynx).
  • Visceral motor (general visceral efferent (GVE) which provide the parasympathetic innervation of smooth muscles (i.e. sphincter papilla) and glands (i.e. lacrimal gland).
  • Visceral sensory (general visceral afferent (GA)) which provide visceral sensation that does not reach consciousness (i.e. parotid gland, carotid body, intestines).
  • General sensory (general somatic afferent (GSA)) which convey information from the skin and mucus membranes (i.e. touch, pressure, heat).
  • Special sensory (special visceral afferent (SVA)) which transmit vision, hearing and balance.
