the only division of the trigeminal nerve to contain a
motor component.
It has three sensory branches (auriculotemporal, buccal and mental) that supply the area of skin derived from the embryonic mandibular prominence, and also supplies
motor fibres to the muscles of mastication (temporalis, masseter, medial and lateral
pterygoids) as well as the tensor tympani, tensor veli palatini, the anterior belly of
digastric and the mylohyoid muscles.
derived form embryonic madnibular division.
The main trunk of the mandibular division gives off two branches; a meningeal branch which supplies the meninges in the middle cranial fossa, and a branch to the medial pterygoid
muscle, which gives off two further branches to the tensor tympani and tensor veli palatini
muscles.
As the main trunk of the mandibular division descends, it divides into a small anterior and a
large posterior part.
