Brain and spinal cord
Peripheral nerves
Neurons and synapses
Spinal nerves and ganglia
The peripheral nervous system includes:
Brain and spinal cord
Somatic and autonomic nervous systems
Cerebrum and cerebellum
Synapses and neurotransmitters
The main function of this nervous system is to incorporate the information it is getting and systematize the information so that it can queue a proper response? This system is also composed of the brain and the spinal chord.
