What happens when we touch a hot kettle?
A Skin → Nerves → Hand is pulled back
B Skin → Nerves → Spinal cord → Nerves → Hand is pulled back
C Skin → Brain → Nerves → Hand is pulled back
D None of these
without brain there would be no reflex. Spinal cord is just a carrier through neurons..it's the brain which signals to pull back the hand from a hot kettle...not any other organs.
The answer B is correct because the Spinal Cord controls the Reflex Actions and if we touch a hot kettle and move our hand back, its a Reflex Action of course!!!
