Flexion is a movement that primarily occurs in the sagittal plane. The sagittal plane divides the body into right and left parts and is responsible for movements like flexion and extension. These movements involve decreasing and increasing the angle between body parts, respectively. In contrast, other planes like the frontal plane govern movements such as abduction and adduction, while the transverse plane involves rotational movements.
| Plane | Movement |
|---|---|
| Sagittal | Flexion, Extension |
| Frontal | Abduction, Adduction |
| Transverse | Rotation |
