Someone recently asked me what the strongest muscle in the human body was. I had thought that, ounce for ounce, it was the tongue. But, turns out there are many ways to measure strength. I came across this website, EverydayMysteries . Interestingly, the myometrial layer of the uterus is one of the strongest muscles. This is the muscle that a woman uses to push the baby out of the body during labor. Usually muscles atrophy with lack of use, but here, a muscle you almost never ‘use’, comes into play for this impressive performance. What a trulyamazing design!
