Which plane divides the body into left and right halves?

• A. Transverse
• B. Frontal
• C. Coronal
• D. Sagittal

Answer: (D)

The key idea is how the body is sliced along planes. The sagittal plane is a vertical plane that runs from front to back and divides the body into left and right portions. When this plane passes exactly through the midline, it creates equal left and right halves and is called the median (mid-sagittal) plane. In contrast, a frontal (coronal) plane divides the body into anterior (front) and posterior (back) parts, and a transverse plane divides it into superior (top) and inferior (bottom) parts. So the plane that yields left and right halves is the sagittal plane, with the midline version specifically producing equal halves.
