Deep temporal nerves

Deep Temporal Nerves

Deep temporal nerves.

The Deep Temporal Nerves are branches of the mandibular nerve, the third division of the trigeminal nerve, which supply the temporalis muscle.

Anatomy

The deep temporal nerves are two in number, anterior and posterior. They ascend between the temporalis and the pericranium. The anterior communicates with the middle temporal nerve, and gives filaments to the temporalis. The posterior, smaller than the anterior, supplies the deep part of the temporalis, and communicates with the auriculotemporal nerve.

Function

The deep temporal nerves carry motor fibers to the temporalis muscle, which is involved in mastication. They also carry sensory fibers from the temporalis muscle to the trigeminal ganglion.

Clinical significance

Damage to the deep temporal nerves can result in weakness or paralysis of the temporalis muscle, which can lead to difficulties in chewing.
