Ontogeny of relationship of middle ear and temporomandibular (squamomandibular) joint in mammals. II. Morphology and ontogeny in insectivores.
The ontogeny of the mandibular joint and the middle ear region was studied in Erinaceus europaeus, Sorex araneus, Talpa europaea and Elephantulus rozeti. During development, a passage connection was found between the mandibular condyle and Meckel's cartilage that is produced by the primordium of the lateral pterygoid muscle. The articular disk is formed apart and it appears later in development.
