Unstriated muscle: (i) The cells of unstriated muscles are long, pointed at the ends and uninucleated. (ii) These muscles are present in alimentary canal, blood vessels, iris of the eye, ureter and bronchi. Cardiac muscle: (i) The cells of cardiac muscles are cylindrical, branched and uninucleated.Read more
