tem·po·ra·lis mus·cle

(tem-pŏr-ālis mŭsĕl)
Origin, temporal fossa; insertion, coronoid process of mandible and anterior border of ramus; action, elevates mandible (closes jaw); its posterior, nearly horizontally-oriented fibers are the primary retractors of the protruded mandible; nerve supply, deep temporal branches of mandibular division of trigeminal.
Synonym(s): musculus temporalis [TA] , temporal muscle.

The EMG recordings showed that children diagnosed with CLP and pain-related TMD have greater temporalis and masseter muscle activity at rest, reduced temporalis muscle activity during maximum voluntary contraction, and a higher Asymmetry Index for the temporalis and masseter muscles in the rest position.
The opening and closing operation of the mouth when humans breathe through the mouth is achieved through the expansion and contraction of the temporalis muscle. As there is a deformation in the shape of the adjacent ear canal due to the expansion and contraction of the temporalis muscle, this change can be measured optically and noninvasively using the ear sensor, to detect mouth breathing.
A newer technique recently described by Takahashi et al involves using a single plate under the temporalis muscle in a hairy area by cutting the anterior site of the bone flap at alternate angles.

Comparison of the mean percentage of maximal voluntary contraction (% MVC) for each muscle among woodwind instruments with a reed mouthpiece (WW-wR), woodwind instruments without a reed mouthpiece (WW-woR), brass wind instruments with a small mouthpiece (BW-SM), brass wind instruments with a large mouthpiece (BW-LM), and control (NW) groups: a) masseter muscle, b) temporalis muscle, c) sternocleidomastoid muscle, d) trapezius muscle
A biopsy specimen was obtained from the temporalis muscle of 1 of these patients.
The craniotomy is made by bluntly dissecting a small portion of temporalis muscle and fascia at the superior temporal line and drilling a 5mm burr hole on the lateral aspect of the exposure below the temporalis for a better cosmetic result.
In this study, with the use of a neuromuscular reprogramming device producing a programmed contact of the anterior teeth for the specific time periods proposed by the study, we observed the highest electromyographic values in relation to the resting position at 0, 5, 10, 15, 20 and 30 minutes for the left temporalis and right masseter muscles; at 0 min for the left masseter muscle; and at 5 and 30 minutes for the right temporalis muscle in normal subjects.

In cluster headaches, the temporalis muscle seems to be involved.
Superior--further divided into deep and superficial based on relation to the temporalis muscle. The deep portion is adjacent to the lateral orbital wall, anteromedial to the temporal tendon.
