GENERAL HISTOLOGY

Detailed explanation-1: -They are called afferent processes because they transmit impulses to the neuron cell body. There is only one axon that projects from each cell body. It is usually elongated and because it carries impulses away from the cell body, it is called an efferent process.

Detailed explanation-2: -Neurons have a large number of extensions called dendrites. They often look likes branches or spikes extending out from the cell body.

Detailed explanation-3: -The axon arises from the soma at a region called the axon hillock, or initial segment. This is the region where the plasma membrane generates nerve impulses; the axon conducts these impulses away from the soma or dendrites toward other neurons.
