Structure
Origin
They usually arise from (the anterior division of) the mandibular nerve (CN V3).[1][2]
Course
They pass superior to the superior border of the lateral pterygoid muscle.[1] They ascend to the temporal fossa[citation needed] and enter the deep surface of the temporalis muscle.[2]
Distribution
The deep temporal nerves provide motor innervation to the temporalis muscle. The deep temporal nerves also have articular branches which provide a minor contribution to the innervation of the temporomandibular joint.[3]
Variation
Number
There are usually two deep temporal nerves - the anterior deep temporal nerve and posterior deep temporal nerve. Occasionally, a third one is present - the middle deep temporal nerve.[2]
Origin
The anterior one may arise from the buccal nerve, and the posterior one may arise from the masseteric nerve.[2]
