IX - glossopharyngeal - SVE
stylopharyngess muscle for swallowing
IX - glossopharyngeal - GSA
general sensation from external ear
IX - glossopharyngeal - GVA

taste to posterior 1/3 of tongue
X - vagus - SVE
muscles of pharynx; larynx
X - vagus - GSA
exteroceptors for skin of earlobe and external auditory meatus
X - vagus - GVA
interoceptors; stretch receptors; chemoreceptors
X - vagus - SVA

XI - spinal accessory - SVE
muscles of larynx
GSA
general somatic afferent
general sensation (touch, pressure, pain, temp) from cutaneous structures and mucous membranes of the head
general proprioception from somatic structures such as muscles, tendons, joints of the head and neck
GSE
general somatic efferent
provide general motor innervation to skeletal muscles derived from embryonic SOMITES
GVA
general visceral afferent
general sensation from visceral
GVE
general visceral efferent
provide visceral motor (parasympathetic) innervation to the viscera
SSA
special somatic afferent
special sensory information from the eye (retina), and from the ear (vestibular apparatus and cochlea)
SVA
special visceral afferent
special sensory fibers from viscera (smell and taste)
SVE
special visceral efferent
supply motor innervation to skeletal muscle derived from BRANCHIAL ARCHES
