An anatomical plane is a hypothetical plane used to transect the body, in order to describe the location of structures or the direction of movements. In human and non-human anatomy, three principal planes are used: The sagittal plane or lateral plane (longitudinal, anteroposterior) is a plane parallel to the sagittal suture. It divides the body ...
The coronal plane, also called the frontal plane, which divides the body into front and back. [2] The transverse plane, also called the axial plane or horizontal plane, which is perpendicular to the other two planes. [2] In a human, this plane is parallel to the ground; in a quadruped, this divides the animal into anterior and posterior ...
The center of the body is defined as the midsagittal or longitudinal plane. [3] These terms come from Latin words with similar meanings, ab- being the Latin prefix indicating ' away ' , ad- indicating ' toward ' , and ducere meaning ' to draw or pull ' .
This plane cuts the body into halves (assuming bilateral symmetry), [3] passing through midline structures such as the navel and spine. It is one of the planes which, combined with the umbilical plane, defines the four quadrants of the human abdomen. [4] The term parasagittal is used to describe any plane parallel or adjacent to a given ...
The frontal plane is the plane that divides the body or an organ into an anterior (front) portion and a posterior (rear) portion. The frontal plane is often referred to as a coronal plane, following Latin corona, which means "crown". [1] The transverse plane is the plane that divides the body or organ horizontally into upper and lower portions ...
The alternate spelling Frankfort plane is also widely used, and found in several medical dictionaries, although Frankfurt is the modern standard spelling of the city it is named for. Another name for the plane is the auriculo-orbital plane. Note that in the normal subject, both orbitales and both porions lie in a single plane.

The human body consists of biological systems, that consist of organs, that consist of tissues, that consist of cells and connective tissue. The history of anatomy has been characterized, over a long period of time, by a continually developing understanding of the functions of organs and structures in the body.
