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.
Hauptachsen
Longitudinalachse (Längsachse)
Die Longitudinalachse zieht sich in kranial-kaudaler Richtung im aurechten Stand durch den Menschen. Diese Achse steht senkrecht zum Boden. Im Bereich, wo Sagittal- und Forntalebene Zusammentreffen bildet sich die Längsachse.
Sagittalachse
Diese Achse verläuft ventral-dorsal und zieht damit von der Körpervorderseite zur Körperrückseite. Sie stellt den Schnittachse der Saggital- und Transversalebene.
Transversalachse (Querachse)
Durch das aufeinander Treffn der Frontal- und Transversalebene bildet sich die Transversalachse. Sie zieht also von links nach rechts durch den Körper und ist parallel zum Boden.
