It controls all voluntary movement, such as speech and walking, and involuntary movements, such as blinking and breathing. It is also the core of our thoughts, perceptions, and emotions.

Electricity produced in the axons of our neurons is the increase and decrease of sodium and potassium levels in a cell.
What are the parts and functions of the nervous system?
Parts of the nervous system, the system of the body that oversees the function of all other systems, include its main organ, the brain; its vessels, the spinal cord and peripheral nerves; and its cells, known as neurons, which transmit the electrical signals that are nerve impulses.
