Q

What 2 formina are located inferiorly in the PPF?

A
  • Greater and Lesser Palatine foramina via palatine canal
17
Q

What nerve brings parasympathetic Activity to the PP fossa?

- Ganglion

A
  • Greater Petrosal N. (VII)

***Pterygopalatine Ganglion
coPs

18
Q

What fiber types are found in the greater petrosal n.?

- BE SPECFIC (pregang./post gang. etc.)

A

GVE - Preganglionic Parasympathetics

SA - taste fibers

19
Q

What areas are ultimately supplied by the Preganglionic Parasympathetics of the Greater Petrosal n.?

A
  1. Lacrimal Gland
  2. Nasal Cavity (minor glands)
  3. Soft palate (minor glands)
20
Q

Where does the SA infromation in the greater petrosal n. come from?

A
  • SOFT palate
21
Q

DEEP petrosal n.

  • Fiber type BE SPECIFIC
  • Job**
A

GVE - sympathetic POSTganglionic

Job:
- VASOCONTRICTION of Blood Vessels

22
Q

Path of the Greater Petrosal n.

A
  1. Exits Hiatus GPN
  2. Runs in Groove GPN
  3. CROSSES carotid canal and Foramen Lac.
  4. JOINS deep PN, and becomes N. of Pterygoid Canal
23
Q

What fibers synapse in the Pterygopalatine Ganglion?

A
  • ONLY Preganglionic Parasympathetics Synapse here

- SA and GVE - symp. fibers pass through

24
Q

What fiber types exist in the N. of Pterygoid Canal?

A

GVE:

  • PRE-ganglionic parasymp (VII)
  • POST-ganglionic symp. (SCG)

SA:
- CN VII

25
Q

What is the only branch of V1 to carry Post-ganglionic parasympathetic fibers from PPG?

A
  • lacrimal n. (V1) via jump from zygomatic n. (?) to lacrimal n.
