Now if we're outside and it's very cold outside, what our body does, the hypothalamus basically induces our somatic nervous system to essentially contract our skeletal muscle. And what this does is it increases the amount of energy that is released and that increases the temperature of our body. It basically helps maintain the core temperature of our body at 36.7 degrees Celsius. In this process is known as shivering. So the skeletal muscle is responsible for the process of shivering when it's really cold outside or when we're very sick. Now let's move on to our structure of our skeletal muscle.
