颞肌怎么了

Temporalis

太阳穴区域极常见

原图集里没有这块肌肉，这一块是顺着颅骨补上的，可以直接点。

这块肌肉是什么

覆盖颞骨（太阳穴）的扇形肌肉，向下附着于下颌骨冠突，是闭口与咬合的主力肌之一，也参与下颌后缩。

为什么会不舒服

精神紧张时无意识咬牙磨牙；低头改变了下颌受力方向；颈椎问题通过三叉神经反射性引起颞肌痉挛；长时间咀嚼坚硬食物。

常见不适表现

太阳穴区域的搏动性头痛或压迫感；咀嚼时太阳穴酸痛；颞下颌关节弹响；张口受限；头痛可放射至眼眶后方和牙齿。

缓解方法

用两指在太阳穴做小圆圈按摩；热敷颞下颌区域；白天有意识地保持上下牙不咬合（牙齿轻微分开，嘴唇闭合）；避免咀嚼坚硬食物。

Temporalis

Temple · Very common

This muscle wasn’t in the original atlas. It was added along the skull, and you can tap it.

What this muscle is

A fan-shaped muscle over the temporal bone, the temple. It attaches down onto the coronoid of the jaw. It is one of the main muscles for closing the mouth and biting, and it also helps pull the jaw back.

Why it gets uncomfortable

Unconscious clenching and grinding when you are tense; looking down changes the direction of force through the jaw; neck trouble can reflexively spasm temporalis through the trigeminal nerve; chewing hard food for a long time.

How it usually feels

A throbbing or pressing headache at the temple; the temple aches when you chew; clicking in the jaw joint; trouble opening the mouth; the headache can spread behind the eye and into the teeth.

What helps

Two fingers, small circles on the temple. Heat over the jaw. Through the day, keep the upper and lower teeth from meeting: teeth slightly apart, lips closed. Avoid hard food.
