The nerve net of a cnidarian carries what?
The nerve net of a cnidarian carries sensory information and coordinates movement and responses to stimuli. This decentralized network allows for quick reactions to the environment.
What type of nervous system do invertebrates have?
Nervous responses in Cnidarians are controlled by a diffuse web of interconnected nerve cells called a nerve net.
What grouping of nerve cells allows a cnidarian to detect the touch of a foreign object?
nerve nets
Does the cniderian have a system?
The phylum Cnidaria encompasses over nine thousand aquatic species. All of these species share common characteristics such as being invertebrates and having no major systems. For example, instead of having a complex nervous system, cnidarians have something called a nerve net which is a simple nervous system. They lack a brain and cephalisation which means the concentration of sensory organs in the head region. However, a nerve net allows the organism to have a response to its environment. In the middle of the nerve net is a nerve ring which allows the cnidarian to swim. An example of an organism with a nerve net is a Hydra.
How does nerve net function?
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 .
Does a cnidarian have a nerves system?
yes they have a simple net nervous system
When the tentacle of a hydra is touched the entire organism responds because?
The nerve net carries impulses in more than one direction.
Do sea anemones have a nerve net?
yes sea anemones have a nerve net.
When was Nerve Net created?
Nerve Net was created on 1992-09-01.
The nerve cells of cnidarians make up a?
The nerve cells of cnidarians make up a simple nerve net. This nerve net allows for basic sensory perception and coordination of movements in these organisms.

Olfactory Nerve
Carries nerve impulses from photoreceptors?
optic nerve
