The understanding of the function and the structure of the nervous system is important for understanding the sensory integration. Neurons produce and transport impulses within, but also between two systems – the central and the peripheral. Sensory integration is organizing the senses for use. Through our senses, we gain information about the physical condition of our body and our surroundings. There are seven sensory systems: vestibular, proprioceptive, tactile, visual, auditive, gustative and olfactory. Disturbance of the sensory integration occurs when the brain inefficiently processes sensory information that comes from one’s own body or surroundings and makes hard for the child to function in activities. The ability to catch, hold and lift an object are the earliest to be noticed in children. These skills, along with watching and listening, are very important for additional learning and exploring the world around us. For that reason, it is important to develop motor skills (coordination, strength, speed, flexibility, stamina, precision) from the earliest age because they are needed by all children to perform large number of activities. A child will more successfully play with toys, whether on its own or with its peer, if it has well developed motor skills. That way, it will spend more quality time in kindergarten or at home. It is important to mention that sensory integration and motor skills are interconnected. Based on that, the educator creates a more stimulating environment for children. In every activity, encouragement and even better development of one or more sensory systems, as well as motor skills, are affected. Activities differ according to the age of children in kindergarten. With younger children, activities are simpler. As they grow, so do the activities get more complex. Children with developmental disorders are being more and more integrated into regular kindergartens and schools.
