Transverse Plane Definition
The transverse plane is an imaginary dividing line that separates the anterior and posterior sections of the body. The transverse plane can also be said to be perpendicular to the sagittal plane and frontal or coronal plane. Both of these planes run with the longitudinal axis of the body, while the transverse plane runs perpendicular to the longitudinal axis. This can be seen in the image below.
In humans, the transverse plane still bisects the longitudinal axis in the same way, but unlike other animals, humans are oriented vertically rather than horizontally. This means that while the transverse plane is usually displayed in the opposite position in diagrams, it is still perpendicular to the longitudinal axis. The transverse plane still separates the anterior portion of the body from the posterior portion, as seen in the image below.
