Cranial Nerve Intro Flashcards
What are the different axon types seen in cranial nerves
GSA GVA GSE GVE SVE SVA
What are SVE
special visceral efferent (just like GSE but the muscle is from a pharyngeal arch)
What is SVA
special visceral afferent
What do GSA neurons utilize in cranial nerves
sensory ganglia
What do GVE neurons utilize in cranial nerves
autonomic ganglia
What do GVA neurons utilize in cranial nerves
sensory ganglia
What do SVA neurons utilize
sensory ganglia
What is the major sensory nerve of the head
Trigeminal nerve CNV
What cranial nerves carry parasympathetics
CN III
CN VII
CN IX
CN X
What cranial nerves will hitch hike on CNV
GVEs from CN III, VI, IX
What nerves will the cervical plexus hitch hike on
CN III
CN XI
CN XII
What is the function of GSE
motor; to skeletal muscle only
What is the function of SVE
motor; ONLY to skeletal muscle derived from a pharyngeal arch
What is the function of GSA
sensation from body wall
What is the function of GVE
parasympathetic; motor to “viscera”
What is the function of GVA
sensation from viscera
