Which plane directly passes through the midline and divides the body into equal halves?

• A. Sagittal Plane
• B. Parasagittal Plane
• C. Frontal Plane
• D. Midsagittal Plane

Answer: (D)

The key idea here is identifying a plane that lies exactly along the body's midline and splits it into equal left and right sides. A sagittal plane runs lengthwise from front to back and is parallel to the midline. When such a plane is right on the midline, it divides the body into equal left and right halves—that specific plane is called the midsagittal (median) plane. If a sagittal plane is offset from the midline, it creates unequal left and right portions and is called parasagittal. The frontal (coronal) plane, on the other hand, divides the body into front and back portions. So the plane that passes through the midline and produces equal halves is the midsagittal (median) plane.
