The temporalis muscle lifts the lower jaw and thus closes the jaw . In addition, its dorsal (back) fibers pull back the lower jaw and thus act antagonistically to the lateral pterygoid muscle . The innervation is provided by the temporal nerves profundi from the mandibular nerve , the third main branch of the trigeminal nerve , i.e. the 5th  cranial nerve .
