What is the primary function of the sagittal plane in human anatomy?

The primary function of the sagittal plane is to divide the body into left and right sections. This anatomical plane runs vertically, parallel to the midline of the body. When the sagittal plane is positioned exactly in the middle, it is referred to as the midsagittal or median plane, creating two equal left and right halves.

Understanding this concept is crucial in various medical and anatomical applications, as it helps in locating structures, diagnosing conditions, and planning surgical procedures. Recognizing the sagittal plane in relation to other anatomical planes such as the coronal (which divides the body into front and back portions) and the transverse (which divides the body into upper and lower portions) highlights its specific role in anatomy.
