Smooth muscle myocyte

 

  

 

This is the myocyte which is spindle-shaped with a nucleus that is centrally placed. The myocyte is the muscle fiber. Its sarcoplasm has longitudinal striations which are indistinct but no transverse striations. The length of a smooth muscle cell or muscle fiber is about 15-500 Ám.

The smooth muscle cell contains myofibrils containing myofilaments actin and myosin disposed in a haphazard manner, hence the smooth appearance of the muscle under the microscope.   It has numerous mitochondria and sarcoplasmic reticulum.   It possesses yellow pigment granules.   Muscle fibers are attached to each other by a cement like substance.
