it is a nerve cell it transfers where the stuff goes through them

A neuron is a nerve cell. One action of a Neuron is it causes reflex actions

Evan L said...

Neurons are nerves tht are basically like cords Sensory neurons respond to stimuli. Thats my comment. THE END

A Neuron is a nerve cell,Neurons send messages to the body.

Neurons are nerves that send signals around the body.

A neuron is a nerve, some of the functions and parts of the neuron include: The long fiber that carries impulses away from the cell body (Axon), Neuron parts that detect the stimulus (Dendrites).

Neurons have a large number of extensions called dendrites. They often look likes branches or spikes extending out from the cell body. It is primarily the surfaces of the dendrites that receive chemical messages from other neurons.

A specialized cell transmitting nerve impulses; a nerve cell.

Sensory neurons: These neurons tell the rest of the brain about the external and internal environment.

Motor (and other output) neurons: Motor neurons contract muscles and mediate behavior, and other output neurons stimulate glands and organs.

Communication neurons: Communication neurons transmit signals from one brain area to another.

Computation neurons: The vast majority of neurons in vertebrates are computation neurons. Computation neurons extract and process information coming in from the senses, compare that information to what’s in memory, and use the information to plan and execute behavior. Each of the several hundred brain regions contain very approximately several dozen distinct types of computational neurons that mediate the function of that brain area.

A neuron is a nerve, cells there are three parts, sensory is one of them and it responds to stimli.

Nerve cells transfer where the things in the body needs to go and a neuron is a nerve.

they have a nucleus

A neuron is a nerve cell. Some parts of a neuron are axons and dendrites. Axons send messages, and then dendrites receive those messages.

Amber R said...

Neurons are nerve cells. They transport impulses.

Ella T. said...

Neurons are nerve cells. Nerve cells send impulses throughout the brain and body and spinal and so on. Axons send impulses and stuff away, dendrites receive.

Most neurons have multiple dendrites, which extend out-ward from the cell body and are specialized to receive chemical signals from the axon termini of other neurons. Dendrites convert these signals into small electric impulses and transmit them inward, in the direction of the cell body. Neuronal cell bodies can also form synapses and thus receive signals (Figure 21-3). Particularly in the central nervous system, neurons have extremely long dendrites with complex branches. This allows them to form synapses with and receive signals from a large number of other neurons, perhaps up to a thousand. Electric disturbances generated in the dendrites or cell body spread to the axon hillock. If the electric disturbance there is great enough, an action potential will originate and will be actively conducted down the axon.

neurons carry messages and emit them to other neurons that eventually travel up to the brain to react to the thing that is hurting or damaging the body

A typical neuron has all the parts that any cell would have, and a few specialized structures that set it apart. The main portion of the cell is called the soma or cell body. It contains the nucleus, which in turn contains the genetic material in the form of chromosomes. Neurons have a large number of extensions called dendrites. They often look likes branches or spikes extending out from the cell body. It is primarily the surfaces of the dendrites that receive chemical messages from other neurons. One extension is different from all the others, and is called the axon. Although in some neurons, it is hard to distinguish from the dendrites, in others it is easily distinguished by its length. The purpose of the axon is to transmit an electro-chemical signal to other neurons, sometimes over a considerable distance. In the neurons that make up the nerves running from the spinal cord to your toes, the axons can be as long as three feet! Longer axons are usually covered with a myelin sheath, a series of fatty cells which have wrapped around an axon many times. These make the axon look like a necklace of sausage-shaped beads. They serve a similar function as the insulation around electrical wire. At the very end of the axon is the axon ending, which goes by a variety of names such as the bouton, the synaptic knob, the axon foot, and so on (I do not know why no one has settled on a consistent term!). It is there that the electro-chemical signal that has travelled the length of the axon is converted into a chemical message that travels to the next neuron.
