Is the heart the strongest muscle in the body

There has been much debate over this. Some people claim
the heart is "strongest" is because it does more work over one's lifetime than any other muscle, and it's almost impossible to fatigue. Another muscle often mentioned is the tongue, although I don't know why--it works almost constantly (at least in some people), but generates little force and does fatigue. Just try sticking it out and wiggling it up and down for five minutes. You'll see. But the strongest muscle in the body is debatable. Some physiologists believe it's the masseter (on either side of your jaw - used for chewing), while others claim it's the gluteus maximus (buttocks), or the rectus femoris (part of the quadriceps in the thigh). It's not easy to determine partly because muscles don't work alone. For example, you wouldn't be able to isolate the rectus femoris muscle and compare it directly to others because other quadriceps muscles contract along with it. There are biomechanical factors to consider as well like muscle length and the points on the bones where muscles attach called the origins and insertions. I guess it is a matter of opinion, but I think the heart is the most important muscle.
