The plane that divides the body into front and back halves is called the sagittal plane.

Here's a breakdown:

* Sagittal plane: A vertical plane that runs from front to back, dividing the body into left and right halves.

* Coronal plane (also called frontal plane): A vertical plane that runs from side to side, dividing the body into front (anterior) and back (posterior) halves.

* Transverse plane (also called axial plane): A horizontal plane that divides the body into upper (superior) and lower (inferior) halves.
