Many descriptions are made using imaginary planes passing through the body in the anatomical position. There are median, sagittal, coronal and horizontal planes.
人们根据解剖方位，设想有多个平面贯穿人体，并由此作出多种描述，即正中面、矢状面、冠状面和水平面。
The Median Plane. This is the vertical plane passing lengthwise through the midline of the body from front to back, dividing it into right and left halves, except for such internal organs as the heart and liver that do not lie in the midline.
正中面。纵向由前向后贯穿人体正中线的垂直面，将人体分为左、右两半，一些不在正中线上的内脏如心、肝等除外。
The Sagittal Planes. These are any vertical planes passing through the body parallel to the median plane. These sagittal planes divide unequally the body to right and left portions.
矢状面。与正中面平行、贯穿人体的垂直面。矢状面将人体分为不对待的左、右两部分。
The Coronal Planes. These are any vertical planes passing through the body dividing it into anterior (front) and posterior (back) portions.
冠状面。贯穿人体的任一垂直面，将人体分为前（正面）后（背部）部。
T\he Horizontal Planes. These are any planes passing through the body at right angles to both the median and coronal planes. A horizontal plane divides the body into superior (upper) and inferior (lower) portions. The horizontal plane sometimes is referred to as the transverse plane.
水平面。与正中面和冠状面呈直角的任何平面。水平面将身体分为上（上面）和下（正面）两部分。水平面有时也称为横断（切）面。
