Which part of the nervous system is made up of cells that send and receive tiny electrical charges?

Hoochie [10]

Answer:

Neurons

Explanation:

Neurons are specialized cells, found in the nervous system, which transmit information.

Neurons contain a dendrite, a soma, and an axon. Some axons are covered with a fatty substance known as the myelin sheath, which surrounds the axon, acting as an insulator and allowing faster transmission of the electrical signal.
