Temporalis Muscle

temporalis muscle is a muscle that receives its name based totally on its region within the frame. 此肌位于颅骨的颞骨扇老式肌肉是颅骨的一侧的骨. 对于颞骨的区域中,常见的时间是寺庙. 颞肌,从颞窝起源 (颞骨的凹陷处) 和颞筋膜 (毛孔和皮肤下位于颞骨上方的腱结缔组织).

从这些位置, the muscle then travels to the mandible (lower jaw) in which it attaches to the coronoid method and the ramus of the mandible. The coronoid technique is a triangular-formed protrusion on the pinnacle of the mandible even as the ramus is the flat part of the mandible this is at once in the back of the enamel.

The Temporalis (Temporal muscle) is an extensive, radiating muscle, situated at the aspect of the pinnacle. It arises from the whole of the temporal fossa (except that part of it that’s shaped by means of the zygomatic bone) and from the deep floor of the temporal fascia. Its fibers converge as they descend, and lead to a tendon, which passes deep to the zygomatic arch and is inserted into the medial floor, apex, and anterior border of the coronoid procedure and the anterior border of the ramus of the mandible almost as ways forward because of the ultimate molar teeth.

In case you touch your temples along with your hands and then chunk down, you may experience a muscle flex outward from the temples. This muscle is the temporalis muscle.

 

颞肌: 功能

The main characteristic of the temporalis muscle is to move the mandible or decrease jaw. Especially, the temporalis muscle elevates the lower jaw with a purpose to chunk or near the jaws. It also features to retract the decrease jaw, 此外, to move the lower jaw from facet-to-side.

Based on those movements of the lower jaw managed by the temporalis muscle, it is simple to peer why it’s far taken into consideration a chewing muscle. By way of shifting the decrease jaw up, again, and aspect-to-side, the temporalis muscle allows you to chunk down and then chunk on meals.
