Our senses (sight, sound, smell, taste, and touch) tell us about our environment. Our senses receive information from both inside and outside of our bodies. Sensory integration (SI for short) refers to how our senses work together to organize and process incoming information from the world around us. The central nervous system (brain and spinal cord) controls our sensory system. When our sensory system works together, it allows us to interact with the environment in purposeful and meaningful ways. 

In addition to the five senses, we also have two special senses, proprioception and vestibular. The proprioceptive sense gives us information about where our body parts are and what they are doing. The vestibular sense gives us information about our position in space and the movement of our head in relation to gravity.
