Which motion is NOT typically associated with the sagittal plane?

The sagittal plane divides the body into left and right halves and is primarily associated with movements that occur forward and backward in this plane. Flexion and extension are the primary motions occurring in the sagittal plane, with flexion referring to a decrease in the angle between body parts and extension being the opposite, where the angle increases.

Hyperextension is another motion that occurs in the sagittal plane, where a joint may extend beyond its normal range of motion, leading to greater angles than typical. In contrast, abduction refers to movement away from the midline of the body and is primarily associated with the frontal plane rather than the sagittal plane. Therefore, the motion that does not typically belong in the sagittal plane context is indeed abduction, highlighting the distinction between the planes of movement and their corresponding actions.
