dentrica is incorrectly written, and should be written as "dendrites" being its meaning:
They are branches of the neuron around its cell body that would be like the Crown of a tree which has a trunk, the axon, and roots with synaptic vesicles, bags filled with chemical liquids which, at the beginning of the nerve impulse, go abroad to warn the dendrites of the next neuron that reverse power polarity and continue with the nervous electrical impulse through the system. One of the initiators of the study of neurons was our Ramón y Cajal. The nervous system is a very complex world, with it up thought.
