The main function of the nervous system is to control the body's activities by relaying messages.

Axons send electrical signals away from the cell body.

A neuron is a nerve cell that transmits signals in the nervous system.

The three main parts of a neuron are the cell body, axon, and dendrites.

The cerebrum is responsible for higher brain functions like thought, action, and emotion.

Sensory neurons carry signals from sensory receptors to the central nervous system.
