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.
Does a sea anemone have a nerve net?
Yes - all Cnidarians have nerve nets, simple nervous system where neural pathways are interconnected and is evenly distributed in the organism.
When the tentacle of a hydra is touched the entire organism responds because?
The nerve net carries impulses in more than one direction.
Is your cell an organism or apart of an organism Nerve Cell?
All your cells are part of you, and you are an organism. Nerve cells are included.
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.
Is the nerve cell an organism or apart of an organism?
Part of an organism
The nerve cells of cnidarians make up a?
Nerve Net
What is primitive nerve nets?
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 .
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
What is Functions of the nervous system of the hydra?
nerve net
