EVERYDAY SCIENCE

Detailed explanation-1: -They are part of the peripheral nervous system and carry nerve signals to and from the central nervous system. They are divided into two broad categories, the sensory ganglia and the motor ganglia (which are associated with the autonomic nervous system).

Detailed explanation-2: -A ganglion is a collection of neuronal bodies found in the voluntary and autonomic branches of the peripheral nervous system (PNS). Ganglia can be thought of as synaptic relay stations between neurons. The information enters the ganglia, excites the neuron in the ganglia and then exits.

Detailed explanation-3: -Structure. Ganglia are primarily made up of somata and dendritic structures which are bundled or connected. Ganglia often interconnect with other ganglia to form a complex system of ganglia known as a plexus.

Detailed explanation-4: -The central nervous system is made up of the brain and spinal cord. The peripheral nervous system is made up of nerves that branch off from the spinal cord and extend to all parts of the body.
