Smooth muscle fibers do not have striations like skeletal and cardiac muscle cells do. This is because:

Smooth muscle fibers do not have striations like skeletal and cardiac muscle cells do. This is because:

a) the sarcomeres are smaller than in cardiac muscle cells and skeletal fibers, and arent visible even when smooth muscle fibers are examined microscopically
b) smooth muscle fibers contain only intermediate filaments, which arent arranged in sarcomeres
c) smooth muscle fibers contain thin and thick filaments, as well as intermediate filaments, but none of them are arranged in sarcomeres
d) visceral smooth muscle fibers dont have striations, but multiunit smooth muscle cells do, but these cells are more rare, and so we rarely have a chance to view them with a microscope
e) both b and d are correct
