Different kind of muscles?
Cardiac, skeletal, smooth
Cardiac-heart muscle, helps it pump
Skeletal-helps you move along with bones
Smooth- lines digestive system, blood vessels, involentary processes
Not really. Everyone can have different amount of muscles due to their heredity. Such as small muscles in their face to control winking, eyebrow movement, ect... If you were thinking along the lines of extra major muscles then no. Different races have different body structures and muscle types. Some may have different amounts red muscles and white muscles due to their race which would account for differences in physical abilities
