[Functional morphology of the maxillo-mandibular system in the mini-Lewe minipig. Structures of masticatory muscles in juvenile animals].

The postnatal changes in the structures of the masticatory muscles are explained on the basis of the Sehnenspiegel. The jaw musculature of juvenile miniature pigs is similar in structure to that of adult animals. All Sehnenspiegel can be found in animals that are only 3 d old. Postnatal development of the masticatory musculature takes place on the basis of the pinnation existing prior to birth and consists in secondary pinnation.
