Head and Neck Musculature
Temporalis (Figs. 5, 26) • Usual attachments: From the fossa temporalis and the temporalis fascia to the
coronoid process and ramus of the mandible. • Usual innervation: Branch of the mandibular division of CN5 (Winkler 1991). • Notes: In orangutans the temporalis is usually not divided into a distinct pars
superficialis and a distinct pars profunda, and there is also no distinct pars suprazygomatica (Boyer 1935a, our dissections).
