Structure
Course
The large sensory root of mandibular nerve emerges from the lateral part of the
better source needed
]
The mandibular nerve immediately passes between
nerve to medial pterygoid
from its medial side. The nerve then divides into a small anterior division and a large posterior division.
Branches
The mandibular nerve gives off the following branches:
- From the main trunk (before the division):
- meningeal branch (nervus spinosus) (sensory)
- medial pterygoid nerve (motor)
- From the anterior division:
- masseteric nerve (mixed)
- deep temporal nerves (mixed)
- buccal nerve (sensory)
- lateral pterygoid nerve (motor)
- From the posterior division:
- auriculotemporal nerve (sensory)
- lingual nerve (sensory)
- inferior alveolar nerve (mixed)
- mylohyoid nerve (motor)
- incisive branch (sensory)
- mental nerve (sensory)
