The supraorbital ridge formation in apes is a result of the traction of the masticatory force exerted by the anterior part of the temporalis muscle. This force varies inversely with the ratio of the power arm to the load arm of the mandible. The smaller this ratio, the greater the anterior part of the temporalis muscle and the larger the supraorbital ridge. The size of the ridge is independent of the actual size of the skull. The orang has a larger skull but the smallest brow ridge of the three… Expand
