Sensory Integration (Part 4): The Touch System
THE ANATOMICAL REVIEW – REGISTRATION
The touch system has the biggest receptor area of all the senses. We need constant touch to keep us organized and functioning.
We register touch through receptors in our skin. We register light touch, deep pressure, skin stretch, vibration, movement, temperature and pain from tactile receptors.
