Muscles of the Uterus. The uterus sits in the lower pelvic region. There are three types of muscles in the human body: cardiac, smooth and skeletal. Cardiac muscle makes up the wall of the heart and is responsible for the forceful contraction of the heart. Smooth muscles make up the walls of the intestine, the uterus, blood vessels, and internal muscles of the eye. 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 tongue is often described in biology texts as the strongest muscle in the body. Wikipedia describes it as the strongest muscle in the human body proportional to size.. It is agreed in science circles that the tongue is the strongest muscle. I wish you all the best. In truth, the tongue is not the strongest muscle in the human body.

The masseter entered the Guinness Book of Records in 1992, as the strongest muscle with an achievement of a bite strength of 4,337 N for 2 seconds. Force is another parameter that can help determine the strongest muscle of the body. The muscle that pulls with the greatest force is the gastrocnemius. The largest muscle in the human body is the gluteus maximus. The gluteus maximus is located in your buttocks and its size directly corresponds to the important role it has in your everyday life.
