Masseter (jaw) muscle
A human’s strongest muscle is his or her ‘masseter‘ muscle. The masseter muscle is a thick muscle in the cheek and is located at the back of the jaw. It’s responsible for opening and closing your jaw during chewing. It is the muscle that can generate the largest externally measurable force attributable to the action of a specific, single muscle. Its strength is the result of incredibly densely packed muscle fibers combined with being attached to a short-armed lever. It can close the teeth with a force as great as 55 pounds (25 kilograms) on the incisors or 200 pounds (91 kilograms) on the molars.
