Quizplus · Accepted Answer

Striated muscles, also known as skeletal muscles, control voluntary movements like walking, jumping, and lifting. Smooth muscles, on the other hand, control involuntary movements like digestion and breathing. Therefore, striated muscles move mostly voluntary systems while smooth muscles move involuntary, automatic systems. Option A is incorrect because smooth muscles are not responsible for moving the voluntary system. Option B is incorrect because twitch speed does not differentiate between striated and smooth muscles. Option D is incorrect because both striated and smooth muscles contain actin and myosin fibers.
