Sphenopalatine Fossa

Question 1

How does the SPF communicate with the infratemporal fossa

Answer 1

pterygomaxillary fissure– transmits the sphenopalatine artery

Question 2

How does the SPF communicate with the middle cranial fossa

Answer 2

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

Question 3

How does the SPF communicate with the Orbit

Answer 3

Inferior orbital fissure– infraorbital n (branch of V2)

Question 4

How does the SPF communicate with the nasal cavity

Answer 4

sphenopalatine foramen– transmits nasal n,a,v

Question 5

How does the SPF communicate with the palate

Answer 5

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

Question 11

What is innervated by the anterior superior alveolar nerve

Answer 11

The incisors

Question 12

What is supplied by the palatine nerves

Answer 12

sensory to mucous membranes of soft and hard palate

Question 13

What is innervated by the nasal nerves

Answer 13

mucous membranes of most of the nasal cavity

Question 14

What is innervated by the infraorbital nerve

Answer 14

lower eyelid
some skin of the nose
upper lips

Question 15

What are the two branches of the infraorbital nerve

Answer 15

middle superior alveolar nerve

anterior superior alveolar nerve

Question 16

Where is the sphenopalatine ganglion located

Answer 16

SPF suspended from the maxillary nerve

Question 17

Is the sphenopalatine ganglion sympathetic or parasympathetic

Answer 17

Parasympathetic

Question 18

Where does the sphenopalatine ganglion receive most of its input

Answer 18

nerve of the pterygoid canal = vidian nerve

Question 19

What are the two components of the Vidian nerve

Answer 19

Greater Petrosal nerve

Deep Petrosal nerve

Question 20

What nerves are included in the greater petrosal nerve

Answer 20

Taste fibers from palate

preganglionic parasympathetic fibers

Question 21

What cranial nerve is the greater petrosal nerve a branch of

Answer 21

CN7 Facial

Question 22

What types of neurons are included in the Deep Petrosal Nerve

Answer 22

postganglionic sympathetic fibers from the carotid nerve plexus

Question 23

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

Answer 23

nasal glands
palatine glands
lacrimal glands
=> all secretomotor
