what to they supply?
4 components:
Somatic motor (somatovisceral) in pons (muscles of facial expression)
Visceral motor (visceromotor) in medulla (parasympathetic efferent fibres from facial nerve (away form) pregangionic fibres originate in superior salivatory nucleus (located in pontine tegmettum) causes lacrimation and salivation )
Somatic sensory in medula (sensation around ear, goes to trigeminal nucleus receives the somatic sensory input form 7, 9 and 10)
Visceral sensory in medulla (taste to anterior 2/3 of tongue, its nucleus is situated in nuvleus solitarius in medulla, floor of mouth and palate)
