MICROANATOMY

Detailed explanation-1: -Due to touching the plate, an impulse is registered from our sensory organs to our Sensory Neurons. From there, the impulse travels to the Central Nervous System (Spinal Cord), where the appropriate action takes place. After that, the impulse is transferred back to the muscle, using the motor neuron.

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: -It acts as a communication relay between your brain and your extremities. For example, if you touch a hot stove, the pain signals travel from your finger to your brain in a split second. In just as short a time, your brain tells the muscles in your arm and hand to snatch your finger off the hot stove.

Detailed explanation-4: -Sensory neurons are the nerve cells that are activated by sensory input from the environment-for example, when you touch a hot surface with your fingertips, the sensory neurons will be the ones firing and sending off signals to the rest of the nervous system about the information they have received.
