The strongest muscle in the human body by weight is the masseter. The masseter is primarily responsible for chewing and is located in the jaw, connecting the temporal bone to the mandible. This muscle enables humans to exert a significant bite force when consuming food, even though it may not be the largest muscle by size. The strength of the masseter is particularly notable; it can exert considerable pressure on the molars during chewing, illustrating the importance of this muscle in daily life and nutrition. A well-functioning masseter contributes to effective digestion and overall health.
