What does the median or sagittal plane divide the body into?

The median or sagittal plane is an anatomical reference that divides the body into left and right halves. This plane runs vertically through the midline of the body, allowing for an analysis of symmetrical properties and movement. When visualizing this division, it is important to note that any cut along this plane results in a separation of the body into two equal parts (assuming a perfect bilateral symmetry), thus providing a functional understanding of how the body organizes itself in terms of lateral structures.

The other options describe different planes of division: the top and bottom are divided by the transverse plane, which separates the body into superior (upper) and inferior (lower) portions, while the front and back sections correspond to the coronal (frontal) plane. Upper and lower limbs do not represent an anatomical division facilitated by a single plane and involve different anatomical studies, making the understanding of the median or sagittal plane distinct in its function and relevance.
