PATHOLOGY

Detailed explanation-1: -To feel pain, impulses travel from the receptors in your hand to the spinal cord through sensory neurons. In the spinal cord, the sensory neurons synapse with interneurons that carry impulses to the sensory cortex area of the cerebrum in your brain.

Detailed explanation-2: -The sensory neurons have nerve endings in the skin which carry the impulse, created due to heat, to the spinal cord. The relay neuron transmits it to the effector/motor neuron which makes the muscles move and hand is taken back.

Detailed explanation-3: -The nervous system uses tiny cells called neurons (NEW-ronz) to send messages back and forth from the brain, through the spinal cord, to the nerves throughout the body. Billions of neurons work together to create a communication network.

Detailed explanation-4: -Impulses from the sensory cortex are conducted over interneurons to the prefrontal cortex of the cerebrum to be “recorded” as memories that associate the sight of a hot stove with pain.
