Answer:
Reflex arc
Reflex actions
There are three main types of neuron: sensory, motor and relay.
These different types of neurons work together in a reflex action. A reflex action is an automatic (involuntary) and rapid response to a stimulus, which minimises any damage to the body from potentially harmful conditions, such as touching something hot. Reflex actions are therefore essential to the survival of many organisms.
A reflex action follows this general sequence and does not involve the conscious part of the brain. This is why the response is so fast.
Neurones work together to make a reflex action
Reflex arcs
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.
