MT 30 LAB – H 4 years, 6 months ago Muscle tissue is made up of cells that shorten or contract for your body to move. The tissue is heavily packed with cells and has a good supply of blood vessels. Muscle cells are long and slender and sometimes referred to as muscle fibers. They are typically grouped in bundles or layers enclosed by connective tissue. Your muscle tissue has contractile proteins such as actin and myosin.-
1.Skeletal muscles are voluntary, which means that you control when and how they would move. The nerves present in your somatic nervous system send signals that promote productivity. For instance, you use skeletal muscles in your neck, arm, and shoulder when you reach for a book on a shelf. -
2. Cardiac muscles are involuntary, which means you cannot control them. Also, you can only find it in your heart. They aid in blood circulation throughout your body by assisting your heart. Your autonomic nervous system control these involuntary muscles. Thus, they work without your intervention and cannot consciously control them.

3. Smooth muscles are also involuntary, which means they are uncontrollable. Your organs, arteries, digestive tract, and certain body parts consist of smooth muscle. The autonomic nervous system controls them as well. For instance, the muscles in the urinary system help remove waste and harmful substances from your body.
