Now the somatic nervous system basically innervates skeletal muscle, skeletal tissue. And that means our somatic nervous system is responsible for our voluntary movement. So what allows me to move my arm back and forth is the fact that inside my arm I have skeletal tissue that is innovated by our somatic nervous system, our skeletal muscle. And that's exactly what allows me to move my hand back and forth. Now what about the autonomic nervous system? Well, the autonomic nervous system innervates cardiac muscle and smooth muscle and then also innervates different types of glands found inside our body.
