There are different types of neurones that work together in a reflex action.
This creates an automatic and rapid response to a stimulus, which minimises any damage to 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.
Where two neurones meet there is a small gap, a synapse.
