Ross is cooking himself a meal and he is about to touch a really hot plate as he is serving up
Using the peripheral nervous system, outline how Ross is likely to respond to avoid burning himself
(4 marks)
Solution:
- Ross receives a signal from the skin in his hand that he can sense heat (the skin is the sense organ)
- This signal is sent from the senses via the PNS and then to the CNS
- The PNS sends a signal to the muscles in his hand i.e. 'Remove your hand from this plate now!'
- The muscles in his hand go into action and Ross takes his hand off the hot plate
