The plane that divides the body into left and right halves is called the sagittal plane. Which option lists the sagittal plane correctly among standard planes?

• A. Coronal plane
• B. Sagittal plane
• C. Transverse plane
• D. Axial plane

Answer: (B)

The key idea is how the standard planes describe orientation in the body. The sagittal plane runs from front to back and divides the body into left and right portions. When it passes exactly down the midline, it’s the midsagittal (median) plane, creating equal left and right halves; if it’s offset, it still remains a sagittal plane but with unequal sides. The coronal plane separates anterior (front) and posterior (back) parts, while the transverse (horizontal) plane separates superior (top) and inferior (bottom) parts, and the axial plane is another term commonly used for the transverse orientation in imaging. Since this question asks for the plane that splits the body into left and right, the sagittal plane is the correct match.
