The second brain contains some 100 million neurons, more than in either the spinal cord or the peripheral nervous system, Gershon says. This multitude of neurons in the enteric nervous system enables us to feel the inner world of our gut and its contents.
The axon is a longer, single processes of the cell soma and relay signals towards the tip, which is called synaptic terminal. There are three main types of neurons: (1) sensory neuron, (2) interneuron, and (3) motor neuron. The nerve cells of the central nervous system are all interneurons. In human brain, there are about 100 billion interneurons. Example is the Golgi cell found in the cerebellum. The interneurons receive impulses from the sensory neurons.
