If a muscle attaches from the mandible to a point that is superior to that mandibular attachment,what eccentric function of the mandible at the temporomandibular joints (TMJs)will this muscle most likely have?

Question

Quizplus · Accepted Answer

Muscles that attach from the mandible to a point superior to the mandibular attachment primarily function in elevating the mandible. Therefore, when acting eccentrically (lengthening under tension), these muscles would restrain or slow down the opposite motion, which is depression of the mandible. Eccentric contractions are used to control or decelerate movements, so in this case, the muscle would help control the lowering of the jaw.
