WITHDRAWAL REFLEX

• Protective reflex, helps to avoid noxious stimuli by flexion, hence known as flexion reflex. Ex. Withdrawal of limb if noxious stimuli is applied to the limb. This reflex is poly synaptic
• Withdrawal is achieved by contraction of flexors (the muscle should be excited) and inhibition of extensors (occurs simultaneously).
