Mandibular Division Flashcards
How many motor nerves are there for the muscles of mastication?
5
Describe the distribution of the nerves for the muscles of mastication
- Two to the temporal
- One to the masseter
- One to the medial pterygoid
- One to the lateral pterygoid
What is the auriculotemporal nerve? (Sensory or motor; distribution)
Sensory; Runs backward to supply the area above and in front of the ear
What is the lowest of all the mandibular branches?
The buccal nerve
Buccal nerve, aka
Long buccal nerve
Long buccal nerve, aka
Buccal nerve
Describe the distribution of the buccal nerve
Posterior portion of the mandibular mucobuccal fold
What does the buccal nerve innervate
- Buccal mandibular gingiva up to the mental foramen
- Skin and mucosa of the cheek
What nerve primarily serves the mandibular teeth?
Inferior alveolar nerve
What is the mylohyoid nerve? (Sensory or motor; what does it innervate)
Small motor branch of the inferior alveolar nerve, supplies the anterior belly of the digastric muscle and the mylohyoid muscle
Describe what happens just after the mylohyoid nerve diverges (distribution and what it innervates)
The inferior alveolar nerve enters the mandible through the mandibular foramen; lower teeth
What is the small branch between the mandibular premolars called?
Mental nerve
What is the mental nerve?
Small branch between the mandibular premolars
Describe the distribution of the mental nerve
Comes out through the mental foramen
What does the mental nerve supply?
Labial mucosa and labial gingiva in anterior mandible area
