In which plane does lateral flexion occur in the human body?

Lateral flexion occurs in the frontal plane, which is also known as the coronal plane. This movement refers to the bending of the body to the side, such as when you tilt your torso towards your right or left. The frontal plane divides the body into front (anterior) and back (posterior) sections, making it the correct plane for movements that involve side-to-side actions like lateral flexion.

In contrast, the sagittal plane divides the body into left and right sections and is responsible for forward and backward movements, such as bending at the waist or performing a squat. The transverse plane, also known as the horizontal plane, involves rotational movements and divides the body into upper and lower parts. The terms "horizontal plane" and "transverse plane" are often used interchangeably, but neither pertains to lateral flexion, which is why those options are not correct in this context.
