What are the 3 type of major muscles?

Answer 1

There are visceral muscles, which consist of smooth muscle tissue, which is controlled by the autonomic nervous system and responds to both hormones and neural stimulation. Smooth muscles have no striations, as the nucleus is centrally located. Thus, they are involuntarily controlled. Then, there is cardiac muscle, which is only found in the heart and is also stimulated by neural activity and hormones. Lastly, there are skeletal muscles, which aid in the movement of the body and is mostly attached to bones by means of tendons. These muscles are striated, and are voluntarily controlled. Skeletal muscles can further be sub-divided into two categories: red and white muscles. Red skeletal muscle tissue consists of a chemical not found in the white skeletal muscle called myoglobin. Myoglobin is a protein-like molecule, which aids in the storage of oxygen, which is essential to its function. Thus, this extra molecule is responsible for giving red muscles their coloring.
