Why does a nerve cell need a large number of processes?
A nerve cell is a structural unit of nerve tissue. Its main function is to carry information from organ to organ, and this tissue is also responsible for the implementation of the main criterion of a living organism – irritability. Excitation through the cell is transmitted through the processes. There are two types of nerve cells, dendrite and axon. Dendrites are short and there are more of them than axons; along them, excitation passes to the cell itself. The axon is a large, long process, it is only one in all types of neurons. It receives information from the dendrites and the axon transmits information to another cell or organ. The more dendrites a cell has, the faster and more accurately it will do its job and respond to stimuli. Thus, the more processes a neuron has, the more perfect the organism and the better its adaptability to conditions.
