Paths Of Psym Nerves Flashcards
To Lacrimal Gland
Facial N runs into Geniculate Ganglion
Greater Petrosal arrises at foramen lacerum, exits the nerve through the pterygoid canal which is in the sphenoid bone
Fibers attach to ptergopalatine ganglion, where they then run into zygomatic n
Zygomatic n runs along the inferior and lateral part of the orbit, where it send off communicating branch to lacrimal n
Lacrimal n takes it the rest of the way
Psym to Submandibular and Sublingual Glands
Facial n gives off chorda tympani within facial canal, after geniculate ganglion
Chorda tympani runs over the tensor tympani in middle ear and exits via the petrotympanic fissure to to run into lingual n (Still pre-synaptic fibers here)
From here, chorda tympani runs to submandibular ganglia to give branches to submandibular glands and sublingual glands
Psym to Otic Ganglion
Glossopharyngeal n exits the jugular foramen, and gives off tympanic n
Tympanic n enters the ear through the tympanic canaliculus in petrous part of temporal
Tympanic n makes tympanic plexus in middle ear, which lesser petrosal arises from
Runs through hiatus of lesser petrosal in sphenoid bone, and exits into foramen ovale
Lesser petrosal hits the otic ganglion just medial to foramen ovale, where it then runs with auriculotemporal of V3 to get to parotid gland
