What movement occurs in the transverse plane?

Movement in the transverse plane primarily involves rotational actions around the vertical axis. This plane divides the body into upper and lower sections, and the key characteristic of movements in this plane is their ability to twist or rotate. In the case of rotation, this can be observed in activities such as turning the head from side to side or twisting the torso during a golf swing.

Flexion and extension are movements that occur in the sagittal plane, which divides the body into left and right halves. These movements involve bending and straightening motions, such as bending at the elbow (flexion) or straightening the arm (extension). Lateral flexion, on the other hand, is a movement that takes place in the frontal plane, which separates the body into front and back halves, and involves bending side-to-side.

The defining feature of the transverse plane is that it revolves around the vertical axis, making rotation the only movement that appropriately fits within this classification.
