What is the role of human nerve cells?

Nerve cells are the main functional component of the nervous system. Every part of the system, whether peripheral or central, is made up of neurons that collect and distribute information to make the body function. There are different types of nerve cells that respond to light, sound, touch, and other stimuli. The main function of nerve cells or neurons in the human body is to carry nerve impulses from one part of the body to another part of the body.

Neurons or nerve cells are connected to other nerve cells where electrical nerve impulses originate, are processed, transmitted and received. They are associated with other cells in muscles, organs, or glands.
