Regression lines obtained from the plots of muscle weight versus cranial size indicate that cricetine murids have larger temporalis and internal pterygoid muscles than murine species with the same cranial size. Among the muscles examined, the temporalis grows at the highest rate in both subfamilies. The present findings suggest that a posterior shift of the hemimandible on the non-chewing side, associated with transverse food processing, requires a stronger backward pull of the temporalis than control of the forward chewing movement.}, pages = {2004-02-20--2004-02-20}, title = {ネズミ科キヌゲネズミ亜科とネズミ亜科における咀嚼筋重量の比較}, volume = {2004-02-20}, year = {} }
