     From babies to body builders, we all have muscles. They grow, they bulge (鼓起), they stretch and
sometimes they even painfully pull. But for all the work they do for us, we are still unable to crown one
as "the strongest muscle".
     Instead, a few muscles could claim the title, depending on how strength is measured.
     If the title goes to the muscle that can exert the most force, the victor would be the soleus (小腿肚肌),
according to Gray's "Anatomy". Without this muscle, we wouldn't be able to stand, walk, run or shake
our bodies on the dance floor. If the soleus was not continuously pulling, we would always be falling over
ourselves (although some of us tend to do that from time to time anyway).
     But perhaps the title should go to the muscle that exerts the most pressure. Pressure is different from
force-pressure takes into account the area over which a force is exerted. The muscle that takes the prize
for delivering the greatest amount of pressure is the masseter, or the jaw muscle, according to the book
"Clinical Oral Science" (Reed Educational and Professional Publishing, 1998).
     In 1986, Richard Hofmann of Lake City, Fla., achieved a bite strength of 975 pounds for two seconds,
setting a Guinness Record. Talk about jaw dropping! The jaw is able to clench (咬緊) and chew because
of the masseter muscle.
     Others may argue the muscles used in childbirth are the most powerful.
     When it comes to versatility, perhaps the tongue is the strongest muscle. Its combination of elasticity
(伸縮性) and forcefulness gives us the ability to speak, eat and kiss-all things very desirable on a first date.
However dexterous (靈巧的) it may be though, its power does not match that of muscles such as the soleus.
     If slow and steady wins the race, the heart is certainly a contender for the title. When it contracts, the
muscle pumps about 2 ounces of blood, and is constantly working over a lifetime. Beating about 40 million
times a year, a person's heart will beat approximately 2. 5 billion times by the time of their 70th birthday.
