Nerve Cells
Nerve cells consist of the cell body, the dendrite and the axon. The axon, a so-called cell process, is, if necessary, very long and can thus conduct information over long distances in the body. This transmission takes place electrically.
The dendrites absorb the stimuli and pass them on to the cell body, where they are processed. The message is then transmitted via the axon to the downstream cells of the nervous system.
In our brain alone, there are well over 100 billion nerve cells.
