Hoarseness and a loss of voice are caused by problems with the vocal cords in the larynx. Problems with the vocal cords are common and can be caused by a variety of things. Treatment can help recover your voice faster which may reduce sick time and improve your quality of life.
Your body is composed of three types of muscle: skeletal muscle, smooth muscle, and cardiac muscle. Skeletal muscle makes up 40 percent of your total body weight, and smooth muscle and cardiac muscle each make up 5 percent of total body weight.Your muscles must contract in order to facilitate vital bodily functions.lthough skeletal muscles and smooth muscles serve very different functions, both muscle groups use the same mechanism of contraction called the sliding filament model.
Like skeletal muscle, cardiac muscle contractions are strong, and utilise a great deal of energy. Like some smooth muscle, cardiac muscle can contract without nervous stimulation (i.e. it is myogenic) and this enables the heart to be transplanted.
