Detailed explanation-1: -Simple bilateral systems Longitudinal nerve cords, usually three to five pairs, extend posteriorly from the brain; they are connected by transverse commissures, and smaller, lateral nerves extend from the cords. The lateral nerves give rise to the peripheral nerve plexuses.
Detailed explanation-2: -Animals that exhibit bilateral symmetry typically have head and tail (anterior and posterior) regions, a top and a bottom (dorsal and ventral) and left and right sides. Most have a complex brain that is located in the head, which is part of a well-developed nervous system and may even have right and left sides.
Detailed explanation-3: -neurons and muscles. Bilateral symmetry in the nervous system means an organization of the nervous system: where one side of the nervous system mirrors the other side. that results in both a brain and spinal cord.
Detailed explanation-4: -A typical neuron has several dendrites, normally arranged in an extremely branched fashion, in order to establish contacts with many other neurons. The cell body also known as the soma which includes the nucleus and perikaryon.
