Why are pots made of metal and handles of pots made of plastic?
Metals are good conductors of heat, so the heat from the stove is easily transferred to the food in the pot. Handles are made of plastic because plastic is a poor conductor of heat, so that the heat from the stove is not transferred to your hand when you grab the handle.

What are the sequence of events that occur within the nervous system from the point you touched the hot stove with your hand to the point you jerked your hand away from the stove?
1. Sensory Receptors detect danger(eg. hot stove in this case) 2. Signal is sent through a sensory neuron to the spinal cord 3.Interneuron in the spinal cord relays the message to the motor neuron 4.Motor neuron sends a message to the effector(eg. muscle) 5. Hand jerks away Sensory neuron also sends a sinal to the brain. Sensation of the evernt is detected continuosly but usually after the defensive action has been taken.
