: Can someone please explain why the Lingual nerve (V3) is GSA? According to the dissector it provides the sensory innervation to the mucosa of the anterior 2/3 of the tongue and the floor of the oral cavity. Dr Evey, said today when something needs to go into a solution it is visceral, thus shouldn't the lingual nerve be GVA? The CN handout only lists GSA and SVE as CN V functional components.
WAIT - Dr Tank left out the chorda tympani of the facial nerve hitchhiking with the lingual nerve (of V3). The chorda tympani of the facial nerve is SVA and is doing the taste sensory innervation (SVA) to the anterior 2/3 of the tongue (meaning you need a solution), while the GSA fibers of the lingual nerve (V3) is doing the general sensation (touch, temp, pain, etc) to the anterior 2/3 of the tongue.
