Flashcards in Sphenopalatine Fossa Deck (23):
1

How does the SPF communicate with the infratemporal fossa

pterygomaxillary fissure-- transmits the sphenopalatine artery

2

How does the SPF communicate with the middle cranial fossa

Foramen Rotundum-- transmits V2
Pterygoid Canal (connects to foramen lacerum)--transmits vidian nerve

3

How does the SPF communicate with the Orbit

Inferior orbital fissure-- infraorbital n (branch of V2)

4

How does the SPF communicate with the nasal cavity

sphenopalatine foramen-- transmits nasal n,a,v

5

How does the SPF communicate with the palate

Greater(and lesser) palatine canals-- transmits palatine nerves (V2), arteries and veins

6

What type of neurons make up the maxillary nerve

Sensory only

7

What is innervated by the zygomatic nerve

supply skin over lateral orbit

8

What does the zygomatic nerve communicate with

Has communicating ramus to lacrimal nerve (V1)

9

What is innervated by the posterior superior alveolar nerve

innervates the molars

10

What is innervated by the middle superior alveolar nerve

middle teeth

11

What is innervated by the anterior superior alveolar nerve

The incisors

12

What is supplied by the palatine nerves

sensory to mucous membranes of soft and hard palate

13

What is innervated by the nasal nerves

mucous membranes of most of the nasal cavity

14

What is innervated by the infraorbital nerve

lower eyelid
some skin of the nose
upper lips

15

What are the two branches of the infraorbital nerve

middle superior alveolar nerve
anterior superior alveolar nerve

16

Where is the sphenopalatine ganglion located

SPF suspended from the maxillary nerve

17

Is the sphenopalatine ganglion sympathetic or parasympathetic

Parasympathetic

18

Where does the sphenopalatine ganglion receive most of its input

nerve of the pterygoid canal = vidian nerve

19

What are the two components of the Vidian nerve

Greater Petrosal nerve
Deep Petrosal nerve

20

What nerves are included in the greater petrosal nerve

Taste fibers from palate
preganglionic parasympathetic fibers

21

What cranial nerve is the greater petrosal nerve a branch of

CN7 Facial

22

What types of neurons are included in the Deep Petrosal Nerve

postganglionic sympathetic fibers from the carotid nerve plexus

23

What types of glands are effected by the postganglionic parasympathetic of the sphenopalatine

nasal glands
palatine glands
lacrimal glands
=> all secretomotor
