12

What nerve runs through the pterygopalatine fossa? What are its two main branches

  • maxillary nerve
  • zygomatic and infraorbital 

13

What ganglion comes off of the maxillary nerve (CN V2)

pterygopalatine ganglion 

14

What nerves come off of the pterygopalatine ganglion? What are their destination?

  • greater and lesser palatine nerves -> palatine canal
  • Nasopalatine nerve -> spehnopalatine foramen

15

Do greater and lesser palatine nerves synapse at pterygopalatine ganglion?

No, they pass through and pick up hitchhikers from the ganglion and exit via the palatine canal

16

The nerve of the pterygoid canal is formed from what two nerves?

  • greater petrosal nerve
  • deep petrosal nerve

A image thumb
17

What is the greater petrosal nerve

nerve from facial n. (CN VII) carrying preganglionic, parasympathetic

A image thumb
18

What is the deep petrosal nerve?

Nerve from the internal carotid plexus off of the superior cervical sympathetic ganglion carrying postganglionic sympathetic innervation 

19

Where does the nerve of the pterygoid run through to get to the pterygopalatine ganglion?

pterygoid canal 

20

Which nerves of the nerve to pterygoid canal synpase in the pterygopalatine ganglion?

  • only parasympathetics: from greater petrosal n. 

21

What arteries run through the pterygopalatine fossa

deep branches of maxillary artery

A image thumb
22

The descending palatine artery off of the maxillary artery parallels what nerves?

greater and lesser palatine nerves -> travel through palatine canal 

A image thumb
23

The sphenopalatine artery off of the maxillary artery parallels which nerve branch?

nasopalatine nerve -> travels through sphenopalatine foramen 

24

What two maxillary arteries parallel the posterior lateral nasal and infraorbital nerves respectively?

posterior lateral nasal artery -> travels to sphenopalatine foramen

infraorbital artery -> travels to inferior orbital fissure
