Detailed explanation-1: -Reflex actions There are three main types of neuron: sensory, motor and relay. These different types of neurons work together in a reflex action .
Detailed explanation-2: -Figure 3-Reflex path showing the five components of a reflex: sensor, sensory neuron, interneuron, motor neuron, and muscle.
Detailed explanation-3: -Most reflex arcs involve only three neurons. The stimulus, such as a needle stick, stimulates the pain receptors of the skin, which initiate an impulse in a sensory neuron. This travels to the spinal cord where it passes, by means of a synapse, to a connecting neuron called the relay neuron situated in the spinal cord.
Detailed explanation-4: -Spinal Cord is the center that controls reflex action.
