What body plane divides the body into equal left and right sides?

• A. Frontal
• B. Transverse
• C. Coronal
• D. Mid-sagittal

Answer: (D)

The main idea here is how body planes partition the body. The mid-sagittal plane, also known as the median plane, runs along the body's midline from front to back and divides it into equal left and right halves. It’s the special sagittal plane that yields equal sides, whereas a sagittal plane elsewhere would cut the body into unequal portions. The frontal (coronal) plane runs vertically to separate front from back, and the transverse plane runs horizontally to separate top from bottom.
