Does anyone know what is the STRONGEST Muscle in the body?

Answer 1

I believe the tongue

Answer 2

i am not sure but i do know the most powerfull muscle is definetly the tounge as it can cause wars,fights,arguments,its also a sex tool,and it can be used for insulting people just by sticking it out (raspberry),I do know its not the Heart as suggested by some, as the Heart has muscle tissue completely different to all other muscle on the body,the myocardium is split into 4 seperate chambers,,the upper chambers are called the atrium l+r,the lower are called the ventricles L+R,blood from the lungs (o2 saturated) enters the right atrium and when full the heart opens up a small valve (mitral)which lets the blood fall into the Right Ventricle(the largest and strongest chamber in the heart)when the heart beats via the atrial node, it causes the ventricle to contract and push the blood up via the aorta into all the various body parts,the other side of the heart does the same job but it collects the blood after the o2 has been collected by various tissue in the body ,the blood is now a darker colour due to the abscence of the o2, this time the left ventricle pumps the blood back to the lungs where it awaits re-oxygenation via the avioli(microscopic air sacs)where the waste products are eliminated from the body and new o2 is collected before the process starts once again,(deffusion)so the heart is very busy and durable but due to the four sections as explained it is not the strongest,,
thanks

Answer 3

Depending on what definition of "strongest" is used, many different muscles in the human body can be characterized as being the "strongest."

In ordinary parlance, muscular "strength" usually refers to the ability to exert a force on an external object—for example, lifting a weight. By this definition, the masseter or jaw muscle is the strongest. The 1992 Guinness Book of Records records the achievement of a bite strength of 975 lbf (4337 N) for two seconds. What distinguishes the masseter is not anything special about the muscle itself, but its advantage in working against a much shorter lever arm than other muscles.

If "strength" refers to the force exerted by the muscle itself, e.g., on the place where it inserts into a bone, then the strongest muscles are those with the largest cross-sectional area at their belly. This is because the tension exerted by an individual skeletal (striated) muscle fiber does not vary much, either from muscle to muscle, or with length. Each fiber can exert a force on the order of 0.3 micronewton. By this definition, the strongest muscle of the body is usually said to be the quadriceps femoris or the gluteus maximus.

Again taking strength to mean only "force" (in the physicist's sense, and as contrasted with "energy" or "power"), then a shorter muscle will be stronger "pound for pound" (i.e., by weight) than a longer muscle. The uterus may be the strongest muscle by weight in the human body. At the time when an infant is delivered, the human uterus weighs about 40 oz (1.1 kg). During childbirth, the uterus exerts 25 to 100 lbf (100 to 400 N) of downward force with each contraction.

The external muscles of the eye are conspicuously large and strong in relation to the small size and weight of the eyeball. It is frequently said that they are "the strongest muscles for the job they have to do" and are sometimes claimed to be "100 times stronger than they need to be". Eye movements, however, probably do "need" to be exceptionally fast.

The unexplained statement that "the tongue is the strongest muscle in the body" appears frequently in lists of surprising facts, but it is difficult to find any definition of "strength" that would make this statement true. Note that the tongue consists of sixteen muscles, not one. The tongue may possibly be the strongest muscle at birth.

The heart has a claim to being the muscle that performs the largest quantity of physical work in the course of a lifetime. Estimates of the power output of the human heart range from 1 to 5 watts. This is much less than the maximum power output of other muscles; for example, the quadriceps can produce over 100 watts, but only for a few minutes. The heart does its work continuously over an entire lifetime without pause, and thus can "outwork" other muscles. An output of one watt continuously for seventy years yields a total work output of 2 to 3 ×109 joules.

Answer 4

Answer: To the best of our belief, the most powerful muscle in the body is probably the gluteus maximus.
This is the muscle that makes up the buttock region of the body and is also one of the body's largest muscles.
It starts from the external surface of the ileum and dorsum of the sacrum (pelvic region). The gluteus maximus extends the thigh and helps in rotating movements. This muscle is the main extender of the thigh. It also functions to raise the trunk of the body from a flexed position.

Answer 5

The heart, because it's constantly in use.But if we're addressing ability to exert pressure, the jaw muscles can exert up to 400 pounds of pressure.

Answer 6

For men it's their eyes (lots of women to look at). For women it's their jaw muscles!!! Actually it is the tongue, believe it or not.

Answer 7

I would've thought the heart. After all it had to circulate all your blood around you.

But as to lifting weight, I'm not sure.

Answer 8

The heart I think.

Answer 9

The aorta (heart)

Answer 10

The tongue I think
