Which plane divides the body into anterior and posterior portions?

Which plane divides the body into anterior and posterior portions?

• A. Sagittal plane
• B. Frontal plane
• C. Transverse plane
• D. Longitudinal axis

Answer: (B)

Understanding anatomical planes that describe how we slice the body helps explain movement and orientation. The plane that divides the body into front (anterior) and back (posterior) parts is the frontal plane, also called the coronal plane. It runs vertically from top to bottom and separates the belly side from the back. This contrasts with the sagittal plane, which splits left and right; the transverse plane, which splits upper and lower sections; and the longitudinal axis, which is a direction through the body rather than a dividing plane. So, the frontal plane is the one that divides anterior and posterior.
