Abstract: It has long been recognized that the masseter muscle of men and women differ with respect to size, activity patterns, as determined from electromyographic recordings, and muscle fiber-type composition, the latter established from classical histochemical analyses. We are studying craniofacial muscles, including the masseter, in several mammalian species and have acquired evidence of marked sexual dimorphism at the molecular and cellular levels in each studied species, including humans. The results of these studies will be presented and how the sex-related differences potentially impact muscle function will be discussed.
