|
1. N. to medial pterygoid
2. Masseteric n 3. Deep temporal nerves 4. Nerve to lateral pterygoid 5. Mylohyoid nerve |
|
What 3 muscles are innervated by the nerve to medial pterygoid?
|
-Medial pterygoid
-Tensor tympani -Tensor veli palatini |
|
What 2 muscles are innervated by the Mylohyoid nerve?
|
-Mylohyoid
-Digastric anterior belly |

2. Buccal 3. Auriculotemporal 4/5. Inferior alveolar -incisive branch -mental branch 6. Lingual n |
|
What does the meningeal nerve get sensory ifno from? (2 things)
|
1. Dura in middle cranial fossa
2. Mastoid air cells |
|
How does the meningeal nerve get thru the cranium?
|
Thru foramen spinosum with the middle meningeal artery.
|
|
What does the buccal nerve get sensory info from?
|
1. Skin of buccal region
2. Mucosa of cheek |
|
How does the buccal nerve get there?
|
Pierces tendon of the temporalis muscle
|
|
What 4 places does the auriculotemporal nerve recieve sensory info from?
|
1. TMJ joint
2. Anterior auricle 3. External acoustic meatus 4. Skin of temple and lateral scalp |
|
How does the auriculotemporal nerve travel?
|
It encircles the middle meningeal artery.
|
|
The 3 branches of the inferior alveolar nerve are:
Which are sensory/motor? |
1. Incisive - sensory
2. Mental - sensory 3. Mylohyoid - motor |
|
What does the incisive nerve get sensory info from?
|
Mandibular teeth
|
|
How does the incisive branch get to the teeth?
|
Runs deep to the lateral pterygoid, through the mandibular foramen and into the mandibular canal.
|
|
What 3 areas are innervated by the mental branch of the inferior alveolar nerve of V3?
|
1. Chin skin
2. Lower lip skin/mucosa 3. Gingiva |
|

|
1. Mandibular gland
2. Mucosa of ant 2/3rds of tongue 3. Oral cavity floor/gingiva mucosa |
|
What is special about the auriculotemporal nerve?
|
It conveys postganglionic parasymp secretomotor fibers of CN IX from the otic ganglion to the parotid gland.
|
|
What is special about the lingual nerve?
|
It conveys preganglionic parasympathetic secretomotor fibers of CN VII to the submandibular ganglion.
|
|
What else does the lingual nerve convey that's special?
|
SVA fibers (taste) to chorda tympani (to CN VII)
