A nerve net is a type of simple nervous system that is found in members of the cnidaria and echinodermata phyla . Nerve nets consist of interconnected neurons lacking a brain or any form of cephalization. This nervous system allows cnidarian to respond to physical contact. They may then detect food and other chemicals in a rudimentary way. Although the nerve net allows the animal to respond to its environment, it has trouble alerting the animal from where the is coming. For this reason, simple animals with nerve nets, such as haunda, will typically respond in the same way to contact with an object, regardless of where the contact occurs.
Hydra, which are cnidarians, have a nerve net throughout their body. On the other hand, , which are echinoderms, have a nerve net in each arm, connected by a central radial nerve ring at the center. This is better suited to controlling more sex movements than a diffuse nerve net .

∙ 9y agoThe nerve net is the simplest form of a nervous system found in multicellular organisms. These nets allow the organism to sense objects through the sensory neurons of the nerve net.
