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 ...
A plane is an imaginary two-dimensional surface that passes through the body. Three planes are commonly referred to in anatomy and medicine: [1] [2]: 4 The sagittal plane is the plane that divides the body or an organ vertically into right and left sides.
Sagittal, a vertical plane that passes from between the nostrils, and between the cerebral hemispheres, dividing the brain into left and right halves. "Median plane" specifically defines the midline between left and right sides of the body. It contains the dorsoventral and medial axes of the brain.

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 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 core or trunk is the axial (central) part of an organism's body. In common parlance, the term is broadly considered to be synonymous with the torso, but academically it also includes the head and neck. Functional movements are highly dependent on this part of the body, and lack of core muscular development can result in a predisposition to ...
