The role of the maxillary muscles involves, as already pointed out in discussing the mandible, mainly the promotion of gnawing by holding the food in the mouth and admitting it to the oral opening. The evolvement and number of the several muscles is directly proportionate with the development and modification of the oral type

. The nerves of the main nerve trunk (nervus maxillaris, Fig. 4) innervate the diverse parts of the maxilla and its muscles. Its first lateral branch extends into the cardo, emitting the sensory nerve or berves of the nervus cardalis and the motoric nerves of the musculus cardalis abductor and adductor (n - 15, n - 16). In some types, the main nerve trunk may constitute a ganglion (g. maxillare), and then emit another lateral branch comprising 2 nerves. The first of these is the motoric nerve of the musculus tentorio-stipialis (n - 17), the second that of the musculus cranio-lacinialis (n - 18). The third lateral branch of the main nerve trunk innervates the muscle between the stipes and the lacinia (n - 19). The fourth lateral branch contains the nerves innervating the motoric muscles of the palpus maxillaris (n - 20, n - 21). The fifth lateral branch is the nervus lacinialis itself. Beyond this,the nervus maxillaris contains further 4 motoric nerves and 2 sensory nerves which latter extend into the maxillary palp and the galea, respectively. The four motoric nerves belong to the musculus stipitogalealis, and the m. palpi maxillaris medialis, ventralis, and dorsalis (n - 22-25). A rovarfej összehasonlító anatómiai vizsgálata II. Regio mandibularis és r. maxillaris izmai és idegei Irta: Dr. Steinmann Henrik Természettudományi Múzeum, Budapest Szerző a tipikus rovarfejről sorozatosan közre adja a feji régiók sorrendjében a rovarfejre közösnek mondható izmokat és idegeket. Jelen közleményben a rágó és az állkapocs régiójának izmait és idegeit foglalta össze.
