Where is the strongest muscle in your body located?

There are, arguably, three answers to this question.

The strongest skeletal muscle is usually said to be the Masseter, a relatively small and squarish muscle that creates movement at the temporomandibular joint (TMJ) or, in lay terms, the jaw. To be more specific, the masseter is considered the strongest muscle for its size. The masseter is easily located on the lateral portion of the mandible (jawbone), just inferior to the ear. Clenching the teeth fires (contracts) this muscle, making it easy to palpate. There are many muscles that are larger (the Gluteus Maximus comes to mind) but again, for its size, the masseter is usually considered the strongest skeletal muscle based on the work it is required to do relative to its size.


The tongue could be considered a legitimate answer to this question. One unique characteristic about the tongue is that it is the only piece of muscle tissue that does not attach to a bone on both ends. The tongue is the primary organ involved in taste and is incredibly strong. It is attached to a horse shoe shaped bone in the throat called the hyoid. The hyoid bone is unusual in that it does not articulate with (form a joint with) any other bone. It is anchored in the throat by thyroid ligaments and provides an attachment site for several muscles.


Yet another answer to this question could be the heart. While the heart is not skeletal muscle tissue, like the muscles that move your bones, it is still a muscle. The heart is comprised of a kind of tissue called cardiac muscle tissue. Because your heart is constantly beating, it is a very strong muscle.
