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 .

What is the function of sacral nerve?
Autonomic nerve function in body
Do cnidarians have a nervous system, and if so, how does it function in comparison to other organisms?
Yes, cnidarians have a simple nervous system called a nerve net. This nerve net is decentralized and lacks a central brain, unlike more complex organisms. Instead, the nerve net allows for basic responses to stimuli, such as movement and feeding, without the need for a centralized control system.

Is the vagus nerve sympathetic or parasympathetic in its function?
The vagus nerve is primarily parasympathetic in its function.
Do hydra have nerve tissue?
The hydra has a nervous system characterized by a nerve net. A nerve net is a collection of separate, but "connected" neurons. Neurons are connected by synapse. Communication between neurons can be in both directions at the synapse within a nerve net. The nerve net is concentrated around the mouth. Unlike higher animals, the hydra does not have any grouping of nerve cell bodies. In other words, there are no ganglia. The hydra does have specialized cells for touch and chemical detection.
The nerve net of the cnidarians is made of primitive nerve cells called?
neuroepithelial cells
