Step 1

Bilateral symmetry is a characteristic of organisms that can be divided into two identical halves by a single plane passing through the center of their body, from the anterior (front) to the posterior (back) end. Show more…

Key Concepts

Bilateral Symmetry

Bilateral symmetry refers to a body plan in which an organism can be divided into mirror-image halves along a single plane. This type of symmetry is a common feature among animals and is important for functions such as movement and sensory processing, as it provides a balanced structure with paired organs and appendages.

Median (Midsagittal) Plane

The median or midsagittal plane is the specific anatomical plane that runs vertically through the midline of the body, dividing it into equal right and left halves. In bilaterally symmetrical organisms, this plane is crucial as it is the one that precisely divides the body into two mirrored sections, revealing the inherent symmetry of the body plan.
