... A. The Neuron- these types of cells are excitable and can send an impulse (electrical signal). Neurons have three major parts: cell body, dendrites, axon. These cells live for many years, do not under mitosis, and are highly dependant on oxygen due to a high metabolic rate. 1. The cell body (soma)- ...
