Question

Which of these is a major difference between skeletal muscle and cardiac muscle? A.Skeletal muscle works very quickly; cardiac muscle works very slowly. B.Skeletal muscle does not fatigue ; cardiac muscle is fatigues quickly. C.Skeletal muscle is involuntary ; cardiac muscle is voluntary. D.Skeletal muscle is fatigues. muscle does not.

Answer 1

• The key difference between skeletal muscle and cardiac muscle is that skeletal muscle is under voluntary control while cardiac muscle is under involuntary control. Muscle tissue is one of the four types of tissues present in the animal body.

Answer 2

D.Skeletal muscle is fatigues. muscle does not.

Skeletal muscle is striated muscle-essentially the fibers slide on each other to shorten and lengthen.
Cardiac muscle is a bit of a mish-mash. It is quite contractile and has striations like skeletal muscle, but also has discs within the structure which speed the contractile process

Skeletal muscle is voluntary and will not contract unless stimulated by a nerve fiber (or an electrode). Cardiac muscle is involuntary and contracts even without nervous stimulation.
