Temporalis

Muscle Origin

Parietal bone to coronoid process of mandible

In humans, it arises from the temporal fossa and the deep part of temporal fascia. It includes the temporal lines on the parietal bone of the skull and the superior temporal surface of the sphenoid bone. The temporal muscle, also known as the temporalis, is one of the muscles of mastication. It is a broad, fan-shaped muscle on each side of the head that fills the temporal fossa, superior to the zygomatic arch so it covers much of the temporal bone. Wiki

Insertion

Coronoid process of the mandible.anatomy-model-muscles-head-805-edited

Action

Elevates, retracts and laterally moves mandible

The anterior portion runs vertically and its contraction results in protrusion of the mandible. The posterior portion has fibers which run horizontally and contraction of this portion results in retrusion of the mandible. If the entire muscle is activated at once the result is elevation of the mandible. Kenhub

Innervation – Nerve control

Deep temporal nerves, branch(es) of the anterior division of the mandibular nerve (V3)

Control of the temporal muscle comes from the third (mandibular) branch of the trigeminal nerve. Specifically, the muscle is innervated by the deep temporal nerves. Wiki

Artery

Deep temporal arteries

The deep temporal arteries, two in number, anterior and posterior, ascend between the temporalis and the pericranium.
