Flashcards in temporal and infratemporal fossae Deck (40):
1

4 muscles of mastication?

temporalis, masseter, lateral pterygoid, medial pterygoid

2

major artery of the infratemporal fossae?

maxillary artery => learn all the branches and where they go

3

pterygomaxillary fissure contains?

ptergypalatine fossa for the pterygpalatine ganglion, it has a spot for greater petrosal n. and deep petrosal n.

4

branch of maxillary to deep face?

after it passes through the sphenopalatine foramen. sphenopalatine artery.

5

temporalis m attaches?

origin @ temporal fossa to coronoid process of mandible

6

medial pterygoid attaches? action?

goes from medial part of the lateral plate to the angle of mandible. moves jaw laterally

7

lateral pterygoid attaches?

right next to the TMJ on the pterygoid fovea and the articular disk

8

scaphoid fossa

where medial pterygoid m attaches

9

foramen ovale has

auriculotemporal nerve that wraps around the middle meningial artery (which is a branch of the maxillary a)

10

greater palatine branches go across to?

they come through the palatine foramina. they pass anteriorly to the hard palate. the Smaller branch goes to the Soft palate

review: what pharyngeal arch makes the pterygoid fovea

second arch. Meckel's cartilage

12

nerve to mylohyoid m.

13

mental spines for?

genioglossus m and geniohyoid m. (innervated by C1)

14

lingular ligament?

sphenomandibular ligament covers the inferior alveolar nerve (gives off nerve to mylogyoid) and inferior alveolar artery

15

where are the four articular disks?

two in TMJ, two in sternoclavicular joint

16

if someone has TMJ, what nerve relays pain?

auriculotemporal, auriculotemporal, masseteric nerves
