Temporal Muscle Anatomy
颞肌解剖学
We will discuss the function and anatomy of the temporalis muscle. The temporal muscle, also known as the temporalis, is a flat, fan-shaped muscle of mastication on the lateral side of the skull.
我们将探讨颞肌的功能和解剖学。颞肌（temporalis）是位于颅骨侧面的扁平扇形咀嚼肌。
It arises from the temporal fossa, a large depression on the side of the skull and the temporal fascia, which completely covers the surface of muscle.
颞肌起自颞窝和颞筋膜，颞窝是颅骨侧面的大凹陷，而颞筋膜则完全覆盖肌肉表面。
From there, the muscle descends through the gap between the zygomatic arch and the skull, forms a thick tendon, and inserts at the coronoid process of the mandible.
然后，颞肌通过颧弓和颅骨之间的间隙下行，形成厚肌腱，止于下颌骨的冠突。
The temporalis is innervated by the deep temporal nerves branching off from the mandibular nerve. You can see the mandibular nerve, highlighted in green, on the image on your screen.
它受下颌神经分支--颞深神经支配。下颌神经如幻灯片图像上的绿色突出区域所示。
Functionally, the muscle can be divided into two parts. The anterior part runs almost vertically and moves the mandible forward, which is known as protrusion. In contrast, the fibers of the posterior part course almost horizontally and pull the mandible backwards, which is known as retrusion.
从功能上讲，颞肌分为两部分：前部几乎垂直走行，使下颌前移，即前突。相反，后部的颞肌纤维几乎水平走行，使下颌骨向后回缩。
The activation of the entire muscle moves the mandible dorsocranially, leading to a strong jaw closure known as elevation.
整块肌肉激活使下颌骨向颅背侧移动，导致下颌强闭合，即下颌抬高。
Due to its size, it can be palpated without difficulty, especially when the mouth is opened and closed. The temporal is the most powerful muscle of the temporomandibular joint.
由于颞肌的大小，我们可以很容易触摸到，特别是嘴巴张开和闭合时。颞肌是颞下颌关节最强有力的肌肉。
