Anatomy Cn V2

Front 1

What bones border the pterygopalatine fossa?

Back 1

pterygoid process of the sphenoid bone posteriorly and the maxilla anteriorly;

Front 2

The pterygopalatine fossa communicates with what on the lateral side?

Back 2

Infratemporal fossa via the pterygomaxillary fissure

Front 3

What are the branches of the 3rd part of the maxillary artery?

Back 3

Posterior superior alveolar artery
Infraorbital artery
Artery of the pterygoid canal
Pharyngeal artery
Greater palatine artery
Sphenopalatine artery

Front 4

What artery supplies the nasopharynx?

Back 4

The artery of the pterygoid canal

Front 5

The greater palatine artery supplies what?

Back 5

the hard palate and then gives off the lesser palatine artery to supply the soft palate

Front 6

V2 Exits the cranial cavity through the foramen rotundum to enter the ____

Back 6

the pterygopalatine fossa

Front 7

The pterygopalatine ganglion is suspended from what nerve, and found where?

Back 7

V2,

in the pterygopalatine fossa

Front 8

The zygomatic nerve enters the orbit through what opening?

Back 8

the inferior orbital fissure

Front 9

Zygomaticotemporal nerve
Has a communicating branch to the

Back 9

lacrimal nerve (V1)

Front 10

What structure passes through the incisive canal?

Back 10

the nasopalatine nerve

Front 11

The posterior superior alveolar nerve, which innervates the maxillary teeth is a direct branch of what nerve?

Back 11

Maxillary

Front 12

The pterygopalatine ganglion contains the cell bodies of what fibers?

It is suspended by ___ by two branches, that we call ____

Passing through the ganglion NOT synapsing includes what other fibers?

Back 12

Postganglionic parasympathetic fibers

V2, Ganglionic branches

Postganglionic SANS and sensory nerve fibers from V2.

Front 13

The pterygopalatine ganglion Receives preganglionic parasympathetic fibers from the ______, which is a branch of the facial nerve at the ___

Back 13

The greater petrosal nerve

geniculate ganglion

Front 14

The pterygopalatine ganglion receives postganglionic sympathetic fibers from the _____, which branches from the internal carotid plexus

Back 14

deep petrosal nerve

Front 15

Describe the pathway of the nerve fibers to the lacrimal gland?

Back 15

postganglionic PANS from pterygopalatine ganglion and Postganglionic SANS from superior crevical sympathetic ganglion reach the maxillary nerve via ganglionic branches. From Maxillary, they branch into zygomatic nerve, then zygomaticotemportal, and finally pass through a communicating branch to the lacrimal nerve (V1)

Back 18

Lesser palatine nerve (lesser palatine canal/foramen)
Greater palatine nerve (greater palatine canal/foramen)
Nasopalatine nerve (incisive canal/foramen)
