Q

V2 function

A

GSA
1 Pterygopalantine: has branches that hang down into the pterygopalantine ganglion, allows for Post gang PS (that synapsed in pt ganglion, from Facial) to go to Zygomatic branch. Form the Pt ganglion it supplies GSA to roof of mouth, soft palate Through Greater and Lesser Palatine
2. Zygommatic: carries postgang PS fibers from above to lacrimal gland. Supplies cutaneous to boney part of check

25
CN 7 names goes through
Facial | enters the internal acoustic meatus runs through facial canal exits through stylomastoid foramen
26
CN 7 branches
``` Temporal Zygomatic Buccal Mandibular Cervical Post auriclar (To Z By Motor Car) Greater Petrosal...to nerve to Pterygoid canal Chorda Tympani (NOT a branch but a "companion") Stapedial ```
27
CN7 does what
SVE motor: these branches go to muscles of facial expression and Stapedius GSA, GVA Has a sensory ganglion: Geniculate ganglion GSA: skin to back of ear, and external acoustic meatus GVA: mucous membranes of nasopharynx GVE Carries Postgang SNS via deep Petrosal meeting with Greater Petrosal PSNS nerve to nerve to Pterygoid canal, PSNS synapse in pt ganglion ---provides SNS to lacrimal gland SVA and GVE: taste Chorda Tympani (nerve intermedius) from descending part of facial nerve comes off before stylomastoid foramen crossed tympanic membrane exits through Petrotympanic fissure and joins lingual, Taste of ant 2/3 tongue and PSNS synapse in submandibular ganglion and innervate Sublingual and lingual gland
28
Geniculate Ganglion
has peudounipolar cell bodies for SENSORY: GSA, GVA and SVA(taste) Runs through facial canal, turns, gives off Greater Petrosal
29
Chorda tympani
SVA and GVE: taste Chorda Tympani (nerve intermedius) from descending part of facial nerve comes off before stylomastoid foramen crossed tympanic membrane exits through Petrotympanic fissure and joins lingual, Taste of ant 2/3 tongue and PSNS synapse in submandibular ganglion and innervate Sublingual and lingual gland
30

37
Glossopharyngeal
GSA, GVA, SVA, SVE, GVE
38
Otic ganglion
receives: Pregang PSNS from glossopharyngeal Postgang SNS form Carotid plexus glossopharyngeal to tympanic to tympanic plexus SNS joins from carotid plexus to make Lesser Petrosal to Otic ganglion pregang PSNS synapse and Postgang to Parotid gland
39

44
CN11 name goes through
Accessory Nerve passes through foramen magnum then out jugular foramen spinal roots that originate from anterior horn of cervical segment
45
CN 11 does
GSE: motor to sternocleidomastoid and trapezius SVE: Cranial component, motor to striated muscle of soft palate, pharynx and larynx
46
