Q

Retromandibular vein is formed by the union of the…

A
  • Superficial temporal vein
  • Maxillary vein
17
Q

The facial vein can also drain into…

A

The cranial cavity

18
Q

What are the deepest contents of the parotid region?

A
  • Auriculotemporal nerve
  • Stylohyoid muscle
  • Posterior belly of the digastric muscle
19
Q

Auriculotemporal nerve

A

Arose within infratemporal fossa to make its way into the parotid region and temporal region to mediate sensation and then innervates the skin

20
Q

Masseter and temporalis innervation

A

CN V3, mandibular division

21
Q

Buccinator action

A

Facial expressions

22
Q

Buccal nerve

A

Motor nerves, courses superficial to masseter n.

23
Q

Long buccal nerve

A

Sensory nerve, emerges deep to the masseter muscle, mediates sensation from the buccal skin and mucosa and gingiva adjacent to the mandibular molar teeth

24
Q

The facial artery and vein crosses what structure, then enters what structure?

A
  • Crosses the mandible
  • Goes through the buccal fat pad
25
Q

Masseter origin

A

Zygomatic arch

26
Q

Masseter innervation

A

Mandible

27
Q

What are the four muscles of mastication?

A
  • Masseter
  • Temporalis
  • Lateral pterygoid muscle
  • Medial pterygoid muscle
28
Q

Temporalis insertion

A

Coronoid process of mandible

29
Q

What type of innervations do all CN V divisions have?

A

Sensory

30
Q

What type of innervations does CN V3 have?

A

Sensory and motor

31
Q

What goes through the mandibular notch?

A

Masseteric nerve and masseteric artery
