It is one of the three main planes of the body used to describe the location of body parts in relation to each other axis.
The coronal plane is an example of a longitudinal plane, because it is perpendicular to the transverse plane. For a human, the mid-coronal plane would transect a standing body into two halves (front and back, or anterior and posterior) in an imaginary line that cuts through both shoulders. The description of the coronal plane applies to most animals as well as humans even though humans walk upright and the various planes are usually shown in the vertical orientation.
The term is derived from Latin corona ('garland, crown'), from Ancient Greek κορώνη (korōnē, 'garland, wreath'). The coronal plane is so-called because it lies in the direction of Coronal suture.
