A nerve is like a cobweb or like a tree's roots. The nerves spread out everywhere throughout your body. Guess what?........... Theirs only one nerve in your body but it spreads out as a tree's branches and takes up the whole body. the nerves are mostly pinkish but sometimes are multicolored.
Although neurons are very diverse and there are exceptions to nearly every rule, it is convenient to begin with a schematic description of the structure and function of a "typical" neuron. A typical neuron is divided into three parts: the soma or cell body, dendrites, and axon. The soma is usually compact; the axon and dendrites are filaments that extrude from it. Dendrites typically branch profusely, getting thinner with each branching, and extending their farthest branches a few hundred micrometres from the soma. The axon leaves the soma at a swelling called the axon hillock, and can extend for great distances, giving rise to hundreds of branches. Unlike dendrites, an axon usually maintains the same diameter as it extends. The soma may give rise to numerous dendrites, but never to more than one axon. Synaptic signals from other neurons are received by the soma and dendrites; signals to other neurons are transmitted by the axon. A typical synapse, then, is a contact between the axon of one neuron and a dendrite or soma of another. Synaptic signals may be excitatory or inhibitory. If the net excitation received by a neuron over a short period of time is large enough, the neuron generates a brief pulse called an action potential, which originates at the soma and propagates rapidly along the axon, activating synapses onto other neurons as it goes.

A nerve cell is an elongated structure, the head or cell body with a tail (which is the direction of the impulse), it looks like the multiple headsets that we see these days. the cell body (Head) has a nucleus within it. the nerves have several points where it branches into dendrites (like the roots on a tuber) the head then extends into a narrow extension which is coated with Myelin sheath. the narrow extension then branches out into dendrites which is a mode of contact to another neuron.
Yo,
The nerve cells are really long and thin. They are insulated t carry electrical messages around the body. xxx hope that helps xxx :) :P
they look like very tiny red spots or "circles." They send messages from the brain , to the whole body! amazing.. These little things make your whole body work !
HAHAHA JOKES! :P
It looks like the roots of a weed.
Human beings ARE animals. It is an idea that comes as an unpleasant surprise to many. The strange thing would be to find that human cells are not like the cells of other animals.
Neurons are eukaryotic cells because they contain the nucleus, just like all other eukaryotic cells.

where do many scientist b human like beings lived
Nerve cells have to be long enough to extend from where they are located in the body, the hands and feet for example, to the spinal chord or brain. Some nerve cells in a giraffe may be ten feet long. Others may be very short.
Human nerve cells are eukaryotic cells, just like every other human cell.
By definition, all human cells are animal cells. Different cells look different from others, no matter the organism. A human nerve looks almost identical to a nerve from a chimp, but a human nerve looks nothing like a cell from a chimp's muscles.

They exist all over your body, they are like needs in the body by becoming specialized; or forming into other kinds of cells like bone, muscle, and blood cells. Also nerve cells.
Neurons are eukaryotic cells because they contain the nucleus, just like all other eukaryotic cells.
The effects of the incorrect disposal of cells is that it usually leads to the pollution of the environment. The incorrect disposal of cells exposes the human beings to heavy metals like lead.
human like beings.

no nerve cells are like a chain one feeels it passes the signal to the next all the way up to your brain
No, they are useful to human beings. For example, you can use it for arrows like yhe other feathers.
It may mean cells that conduct impulses like nerve cells.
YES
