Detailed explanation-1: -Neurons and Glial Cells. The nervous system is made up of neurons, the specialized cells that can receive and transmit chemical or electrical signals, and glia, the cells that provide support functions for the neurons. A neuron can be compared to an electrical wire: it transmits a signal from one place to another.

Detailed explanation-2: -The nervous system uses tiny cells called neurons (NEW-ronz) to send messages back and forth from the brain, through the spinal cord, to the nerves throughout the body. Billions of neurons work together to create a communication network. Different neurons have different jobs.

Detailed explanation-3: -Cells of the nervous system, called nerve cells or neurons, are specialized to carry “messages” through an electrochemical process. The human brain has approximately 86 billion neurons.

Detailed explanation-4: -Neurons are information messengers. They use electrical impulses and chemical signals to transmit information between different areas of the brain, and between the brain and the rest of the nervous system.

Detailed explanation-5: -Neurons are specialized cells that receive and send signals to other cells through fragile and thin cellular extensions called axons.
