Hug from a loved one can lower blood pressure and make people feel valued and important. While the handshake can be the beginning of a relationship. And what about the touch of a perceived sense of skin? The touch is always associated with skin organ, the skin having at least about 5 million a sensory nerve. Although a person can feel pain and pressure in the body, but mostly a sense of touch comes from external stimuli through the skin. As quoted from HowStuffWorks, on Tuesday (8/12/2009) there are few sensations can be felt someone through a touch, namely:
1. Familiarity. People who get a touch from someone who cares with him will cause a sense of warmth and comfort. Pressure sensors will interpret it as a touch of a soothing thing.
2. Healing or therapy. Touches of this kind usually associated with massage or acupuncture. Sometimes gentle pressure which can be given the relief of pain in the muscles so the body feel more relaxed.
3. Exploration or curiosity. Many things can be learned through the senses of touch, such as testing the fabric or objects with different textures to feel. Because of the touch can be used to seek or explore something.
4. Aggressive or painful. Sometimes a touch is given to provide pain if done at the wrong place or too deep to provide pressure.
When a touch occurs, the sensor surface of the skin will be stimulated and sends electronic signals to the neurons are specialized cells that transmit electrochemical impulses back. These neurons will act emit electrical pulses returned from neuron to neuron until it reaches the spinal cord. Spinal cord is the organ that absorbs the incoming signal and sends it to the brain. After receiving signals from the spinal cord, the brain began to translate the signals. For example, if there is something cold touches the skin, the cold receptors in the brain will be activated and respond to shiver.
If you already know what the sensation caused by a touch, the sensation of what you normally feel?
