Which term describes the sagittal section that separates left and right hemispheres?

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

Answer: (A)

The key idea is how planes of section divide the brain. A sagittal plane runs from front to back and splits the brain into left and right halves. A cut along that plane—called a sagittal section—reveals left and right hemispheres. If the cut goes exactly down the middle, it’s called a midsagittal (or medial) section, but the general term for a left-right separating cut remains sagittal section. In contrast, a coronal (frontal) plane separates front from back, and a transverse plane separates top from bottom. So the term that describes the left-right separation is sagittal section.
