Q. What are ganglia?

Neural ganglia or Ganglia (singular ganglion) are structures located outside the central nervous system (for instance, beside the spinal column or near viscera) made of concentration of neuron bodies.

Examples of neural ganglia are the ganglia that concentrate cell bodies of sensory neurons in the dorsal roots of the ganglia of the myenteric plexus and the spinal cord responsible for the peristaltic movements of the digestive tube.

In the central nervous system (CNS) the concentrations of neuron bodies are not called ganglia and actually it is called as nuclei.
