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 muscles are of two major types known as single unit, aka unitary, smooth muscles and multi-unit smooth muscles. The single unit smooth muscles contract and relax together, as the nerve impulse excites only one muscle cell, and that is passed on to other cells through gap junctions. Smooth muscles are found in inner organs while cardiac muscles are found only in the heart. â¢ Cardiac muscles are striated, but smooth muscles are non-striated. â¢ Each cardiac muscle cell has one or more nuclei, but the smooth muscle cells are single nucleated.
