Gnathostomata improved the brachial cartilages of Agnahta into jaws. At the same time, such a jaw formation resulted not only in the development of eye, nose, and ear for searching foods but also in the development of brain which regulates the functions of these sense organs and mastication muscles. In this paper, we described about the muscles, mouth, tongue, and jaw which participate in mastication from a view point of morphology and molecular biology.
