The central nervous system consists of the brain and the spinal cord, the peripheral nervous system consists of nerves and ganglia.
Neurons transmit electrical signals via chemical and electrical synapses.
The main parts of the human brain are the brain stem, the cerebellum, the diencephalon, and the cerebrum, which is divided into lobes.
