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.

Hauptebenen und Hauptachsen am menschlichen Körper
Durch den menschlichen Körpen, können beliebig Viele Achsen udn Ebenen gelegt werden. Um einheitliche Lage- und Richtungsbezeichnungen zu ermöglichen, werden in der Regen drei Haupachsen und -ebenen definiert. Die Achsen und Ebenen sind senkrecht zu einander ausgerichtet.
Hauptebenen
Sagittalebene
Sagittalebenen sind alle vertikal ausgerichteten Ebenen. Sie liegen parallel zur Sutura sagittalis (Pfeilnaht) des Schädels. Beim stehenden menschen verlaufen diese Ebenen von ventral nach dorsal. Die Mediansagittalebene befindet sich genau in der Mitte des Körpers und teilt den Körper in zwei seitengleiche Hälften.
Frontalebene
Die Ebenen, die parallel zur Stirm verlaufen, sind Frontalebenen. Im Stand des Menschens ziehen diese Ebenen vertikal von einer Körperseite zu der anderen.
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.
