部位及取法

运动区相当于大脑皮层中央前回在头皮上的投影。上点在前后正中线的中点向后移0.5厘米处，下点在眉枕线和鬓角发际前缘相交处。（若鬓角不明显者，可从颧弓中点向上引一垂直线，将此线与眉枕线交点前0.5厘米处作为下点)，上下两点之间的连线即运动区。将运动区划分为五等分，上1/5为下肢、躯干运动区，中2/5为上肢运动区，下2/5为面部运动区。

Location

It is located over the anterior central convolution of the cerebral cortex, being a line starting from a point (known as the upper point of the Motor Area) 0.5cm posterior to the midpoint of the anterior-posterior midline of the head and stretching diagonally to the juncture between the eyebrow-occipital line and the anterior border of the corner of temporal hairline is indistinct, draw a vertical line upward from the middle point of the zygomatic arch to the eyebrow-occipital line, the intersection of the two lines is the prohection of the Motor Area. Motor Area is divided into five equal parts: the upper one-fifth being the Motor Area of the lower limb and the trunk, the middle two-fifths being the Motor Area of the upper limb, the lower two fifths, the Motor Area of the face.医学全在线www.med126.com
