Different types of neurones work together in a reflex action.

This creates an automatic, and rapid response to a stimulus, which protects the body from potentially harmful conditions, such as touching something hot.

A reflex action follows this general sequence and does not involve the conscious part of the brain, which makes it much quicker.

The nerve pathway followed by a reflex action is called a reflex arc. For example, a simple reflex arc happens if we accidentally touch something hot.
