Touch is really our first language.
It begins to function in utero and provides us with the ability to begin to understand and react to the world. Our skin is the sensory organ that holds many specific types of touch receptors. We perceive pain and temperature through nerve endings in the different skin layers, within joint capsules, ligaments and tendons. Hair movement, pressure and vibration detection allow us to receive information from our environment. This sensation is then sent as a nerve impulse, to the brain for processing and interpretation.
