How does the heart muscle differ from the muscles of your arm after you lifted a rock a number of times?

The muscles in the heart are involuntary and the ones in your arm are voluntary. What that means is that you can tell your arm what you want it to do, but the heart makes its beat by processes that you cannot consciously control.

∙ 13y agoThe heart muscle is different from smooth and skeletal muscles because it does not require a nerve to cause it to contract. The heart has it's own built in conduction system that cause's the automatic contraction and relaxation that is required for circulation. Smooth and Skeletal muscle whether it uses voluntary or involuntary muscle contraction all have innervation to cause the contraction.

∙ 13y agoEvery muscle comes from it's own particular cell structure. Cardiac muscle is involuntary , and it never rests. You don't have to think to make it work. It is internally charged by a structure called the Bundle of His [ hiss] which initiates an electrical charge to cause the beat . Many things can affect the function , external temperature , diet, hydration, hormones. It is really quite fascinating, and I suggest you look into it in greater depth than I can provide here. I hope I piqued your interest.

Why are skeletal muscle cells multinucleated?
The number of cells depends on how large the muscle is; muscles consist of fiber bundles, which are made up of myofibrils. A sarcomere is one of the segments that the myofibril is divided into. In each fiber bundle there are multinucleate cells, which can extend the length of the skeletal muscle. So, the number of cells in a skeletal muscle depends on the size of the muscle. for example, the number of cells in one of our triceps larger than one of the small muscles in a finger.
