What will you do if someone pricks your hand with a needle? Elucidate

1.	What will you do if someone pricks your hand with a needle? Elucidate the pathway of response with a neat labelled diagram.
Answer» If we touch a sharp pointed object, we immediately withdraw our hand. Here the skin is the receptor and it receives the stimulus, that is the pain. This stimulus (pain) in turn triggers an impulse in sensory neuron. The sensory neuron transmits or convey the message to the spinal cord. Spinal cord interprets the stimulus and the impulse is passed on to the relay neuron which in turn transmits it to a motor neuron. Motor neuron carry command from the spinal cord to our arm. Muscle in our arm contracts and we withdraw our hand immediately
