Smooth muscle. Smooth muscle is also sometimes known as Involuntary muscle due to our inability to control its movements, or Unstriated as it does not have the stripy appearance of Skeletal muscle.Smooth muscle is found in the walls of hollow organs such as the Stomach, Oesophagus, Bronchi and in the walls of blood vessels.t has similarities with skeletal muscles in that it is striated and with smooth muscles in that its contractions are not under conscious control. However this type of muscle is highly specialised.
Skeletal muscle is the voluntary muscle in which contraction occurs with conscious thought; but cardiac and smooth muscles are involuntary in which contraction occurs without conscious thought. Skeletal Muscle. Based on its structure skeletal muscle is called striated muscle.ardiac muscle is specifically found in the myocardium of the heart, and it is a striated and involuntary muscle. Cardiac muscle is composed of cardiac muscle cells, which are called cardiomyocytes, which have one, two, or rarely three or four nuclei.
