Human bodies are complex combinations of systems that work independently and together. One example of an interdependent system is the combination of____________ and muscular systems. These two systems keep our bodies safe from danger presented by outside_________. Your____________ system provides protection for the network of nerves throughout your body. Sensory___________ in muscles detect outside stimuli and help your muscles react accordingly. When danger is detected, sensory receptors send __________ to your brain, which then sends signals to your muscles, making them move to protect your body. For example, if you are looking in the opposite direction and touch a hot stove top, sensory receptors will send a signal to your brain, causing your hand to move quickly. Even though you were not looking in the direction of the stove, your body protected itself with the help of the nervous and muscular systems. Think about other ways your muscular and nervous system work together to protect your body from harm.
