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.
Smooth muscle is the only muscle of this type and without striations, other less obvious characteristics are used to identify this tissue. Before we examine smooth muscle in longitudinal or cross-section, it might be worth our while to determine why some myofibers are striated while others are not.
