Flexion, a movement primarily observed in the sagittal plane, reduces the angle between body parts. The sagittal plane delineates the body into right and left sections and accommodates flexion and extension. Conversely, the frontal plane facilitates abduction and adduction, while the transverse plane governs rotational actions.
