Compared to cnidarians, bilaterally symmetrical animals have a central nervous system.
<h3>What do bilaterally symmetrical animals have?</h3>
• Bilaterally symmetrical animals have "heads" and "tails" (front and back), front and rear (back and abdomen), and left and right sides. All true animals are bilaterally symmetrical, except those with radial symmetry. The
• longitudinal nerve cords, usually in 3-5 pairs, extend posteriorly from the brain. They are connected by transverse commissures, with smaller lateral nerves extending from the cords. The peripheral plexus arises from the lateral nerve.
<h3>Do bilaterally symmetrical animals have diffuse neural networks?</h3>
Neural networks consist of interconnected neurons that lack brains or some form of cephalization. Organisms with bilateral symmetry are usually associated with neuronal compression and, in a more advanced form, with the central nervous system, whereas organisms with radial symmetry are associated with neural networks.
