The nerve cells that detect heat (located within your Dermis) activate when touching a hot surface. This nerve impulse then travels through your central nervous system to your brain when it is translated as "pain" or "damage" to the area. The signal travels back down the arm as a reaction to move the stimulous and causes you to move your hand.
A concrete noun is a word for something that can be experienced by any of the five physical senses; something that can be seen, heard, smelled, tasted, or touched.
The eyes sense light and images, the nose senses odors, the ears sense sound waves, the skin senses touch, temperature, and pain, and the tongue senses taste.
Some examples of other senses include proprioception (sense of body position), vestibular sense (sense of balance and spatial orientation), and thermoception (sense of temperature).
You can observe an object's color, shape, texture, size, weight, smell, taste, and temperature using your senses.
The three skin senses are touch, temperature, and pain. Touch receptors detect pressure, vibration, and texture, while temperature receptors detect hot and cold sensations. Pain receptors, called nociceptors, respond to tissue damage or injury.

An action potential forms :) -Apex-
an action potential moves along the neuron
The neuron in your finger senses the temperature first. It sends a signal to your brain, which then interprets the information and signals your muscles to move your hand away from the heat source.

The first thing that happens when you touch something hot is the activation of specialized nerve endings called thermoreceptors in your skin. These thermoreceptors detect the change in temperature and send a signal to the brain through the neuron to alert you of the heat and trigger a reflex action like pulling your hand away.
You can observe the color, texture, shape, and temperature of an object using your senses.
Ions flow into the neuron. An action potential forms moves along the neuron. A response occurs, here, an aversion response... your body pulls your hand and finger away.
Sensory neurons
The information each neuron processes determines how strong the action potential (electrical current) is within each neuron. An example of studying the electrical activity is by using temperature. The neurons which detect the temperature change are called sensory neurons. If you stimulate the neurons by leaving your fingertip in cold water for an adequate amount of time the electrical current within each neuron is increased as the temperature of your fingertip drops. The neurons within the fingertip sense the temperature drop and emit the electrical current, then the next neuron senses the temperature drop as the fingertip is held in the cold water and emits a stronger electrical current, the colder temperature in the next neuron as your finger is held in the water emits an even higher frequency and so on until the message arrives at the spinal cord and is then sent to the brain through the now very strong electrical current within the neurons informing it of the temperature decrease and then resulting in action outcome.
