e.g. biceps, triceps in the upper arm, leg muscles
2. Smooth muscles – muscles present in the walls of internal organs (wall of intestines, uterus,
bladder) and wall of blood vessels, involuntarily controlled/ contracted
3. Cardiac muscles – present in the wall of heart, involuntary and rhythmic contraction
