Lesson 1: The Skin and It's Sense of Touch

What is touch?

                    - it is the interpretation in the brain of various environmental stimuli that are picked up by nerve endings located in the deep layer of the skin called the dermis.  The sense of touch is found all over the body.  The body has over twenty types of receptors; the most common are heat, pressure, cold, and pain.  Pain receptors are very important to us, as they let us know the body is hurt. This video below will help you understand how the sense of touch works.
