Each neuron has one axon but multiple dendrites extending from the cell body. Multipolar neurons are the most complex and commonly occurring type of neuron within the human body. Their presence in humans is limited, but they play an important role within the ears, nose, and eyes. Unipolar neurons do not occur in humans.īipolar neurons have one axon and one dendrite extending from the cell body. The axon splits up into dendrites at the ends. Unipolar neurons are the simplest form, with one axon extending from the cell body. The arrangement of these components determines the type of neuron. These are the cell body, axons, and dendrites. Other forms, including pseudounipolar and anaxonic neurons, also exist. The three main types of neurons are unipolar, bipolar, and multipolar. Neurons are nerve cells that transfer information around the body, and some types form part of the CNS. However, they do have pseudounipolar neurons.
