Explanation / Answer
1) Temporalis is the muscle that is located in the side of the skull. It is located above and infron of the ear. Its function is similar to the Masseter muscle which is to elevate the lower jaw to close the mouth.
2) Maxilla attaches laterally to the zygomatic bone which is the cheek bone. Maxilla forms the boundaries of the three cavities.
3) Diaphragm is the doom shaped muscle which is inserted into the lower rib. This is the muscle which separates the thoracic cavity. It is the primary muscle which is used in the process of INSPIRATION or INHALATION.
4) The most powerfull muscles of the mastication process are Masseter and Temporal muscles.
5) The movement of shoulder joint is restricted by the pectoralis major.
6) The zygomatic bone articulates with the temporal bone. The zygomatic and the temporal bones are the two bones that makes up the zygomatic arch.
7) The exial skeleton is the part of the skeletal system. It consists of the bones of the head and the trunk of the vertebrateThe axial skeleton is composed by three main components they are 1) Bony thorax, 2) Vertebral column, 3) Skull and the hyoid bone.
