What is a nerve net and how many specialized nerons does a nerve net include?
A nerve net is a simple form of a nervous system found in certain organisms, such as cnidarians (e.g., jellyfish and corals), where neurons are distributed throughout the body in a decentralized network rather than being organized into a central brain. This structure allows for basic sensory and motor functions, enabling the organism to respond to environmental stimuli. A nerve net typically includes a variety of specialized neurons, but the exact number can vary widely among species; it generally consists of hundreds to thousands of interconnected neurons.
Which contains the simplest forms of muscles and nerves- Echinodermata Arthropoda Crustacea Vertebrata Mollusca?
Echinoderms have the simplest nerve and muscle structures among the options given. They have a decentralized nerve net and tube feet with muscles that help in locomotion and feeding. Arthropods, Crustaceans, Vertebrates, and Mollusks have more complex nerve and muscle systems with centralized nerves and specialized muscle fibers.
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.
Is the brain a part of the nervous system of the hydra?
Yes, the brain of a hydra is a part of its nervous system. Hydras have a simple nerve net instead of a centralized brain, which helps them coordinate their movements and responses to stimuli.
Do starfish have a nervous system?
Yes, a fairly crude one. Yes,They have a nerve ring with nerves along each arm.

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.
Do jellyfish have ganglia?
no, just a nerve net which is a collection of separate neurons
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 .

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.
Do jellyfish have a heart and a brain?
Jellyfish do not have specialized digestive, osmoregulatory, central nervous, respiratory, or circulatory systems. A jellyfish does not have a brain or central nervous system, but rather has a loose network of nerves, located in the epidermis, which is called a "nerve net". A jellyfish detects various stimuli including the touch of other animals via this nerve net, which then transmits impulses both throughout the nerve net and around a circular nerve ring, through the rhopalial lappet, located at the rim of the jellyfish body, to other nerve cells.
What organism has a nerve net?
Grasshopper
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.
The nerve net of the cnidarians is made of primitive nerve cells called?
neuroepithelial cells
