Position and direction designations
By means of position and directional markings on the body, positions, layouts and courses on the body are described. These are different from colloquial designations such as "above" and "below", regardless of the position of the body, for example lying or standing

Introduction
On living bodies there are extended position and directional designations. These serve to provide an exact description of the position, direction and progression of anatomical structures. In contrast to colloquial position words like "above" and "below", the description is independent of the position of the body. In order to recognize the correct position or direction, the basic anatomical position is sometimes necessary. This is the case when a person stands upright, his hands are supinated (palm facing forward), the eyes are straight ahead and the feet are parallel.
.
The human being belongs like many animals to the Bilateria (two-sided animals). That means the body is bilaterally symmetrical and has two mirror-image halves. The median plane represents the mirror plane. This is the only symmetry plane in the body of a bilateral.

Main planes and main axes on the human body
Through the human body, any number of axes and planes can be laid. In order to enable uniform position and direction designations, three main axes and planes are defined in the rain. The axes and planes are aligned perpendicular to each other.
Main planes
Sagittal plane
Sagittal planes are all vertically oriented planes. They are parallel to the sagittal suture of the skull. In a standing person these planes run from ventral to dorsal. The median sagittal plane is located exactly in the middle of the body and divides the body into two halves that are equal on either side.
Frontal plane
The planes that are parallel to the forehead are frontal planes. When the person is standing, these planes move vertically from one side of the body to the other.
Transversalebene
Die Transversalebenen verlaufen horizontal. Sie teilen den Körper jeweils in einen kranialen und kaudalen Teil. Diese Ebenen liegen senkrecht zur Körperlängsachse.
Main axes
Longitudinal axis (longitudinal axis)
The longitudinal axis runs through the human body in a cranial-caudal direction in the right position. This axis is perpendicular to the ground. In the area where the sagittal and the forntal plane meet, the longitudinal axis is formed.
Sagittal axis
This axis runs ventral-dorsal and thus moves from the front of the body to the back of the body. It represents the intersection of the saggital and transverse planes.
Transversal axis
The transverse axis is formed by the meeting of the frontal and transverse planes. It passes through the body from left to right and is parallel to the ground.
