Some muscles (skeletal muscles) will not contract unless stimulated by neurons; other muscles (smooth & cardiac) will contract without nervous stimulation but their contraction can be influenced by the nervous system. Thus, the nervous and muscle systems are closely interconnected.
Some examples of muscles that work independently of conscious thought include smooth muscles in internal organs like the stomach and intestines, cardiac muscle in the heart, and muscles involved in breathing such as the diaphragm. These muscles are controlled by the autonomic nervous system and carry out their functions without requiring conscious input.
