Transverse plane
In a bilaterally symmetrical animal, the transverse plane is the plane passing through the dorsoventral (dorsoventral) and right-left axes and perpendicular to the anteroposterior axis.
The transverse plane divides the animal's body into anterior and posterior parts. It passes through the thoracic and lumbar regions, dividing the torso into thoracic and abdominal sections.
In most animals with bilateral symmetry, the transverse plane divides the body into mirror-symmetrical right and left parts. This allows the internal organs and limbs to be distributed evenly on both sides of the body.
The transverse plane is one of the three main anatomical planes, along with the sagittal (longitudinal) and frontal (coronal) planes. It plays an important role in describing the anatomy and physiology of the body.
