Abstract:
The relations between the osseous palate and its dental laminae in larvalSalamandra salamandra (L.) during metamorphosis were examined by various amputation procedures. Removal of the mucosa and the subepithelial tissue in the region where the differentiation of the osseous bar of the vomer ("Vomerspange") takes place, does not prevent outgrowth of the bar. When this tissue material is transplanted into the subepithelial connective tissue of the body, structures similar to the bar are not formed. Amputation of the vomer and adhering connective tissue prevents the development of the bar, whereas removal of the palatinal part of the pterygopalatinum has no influence on its development. The vomerine bar does not therefore represent a "Vomeropalatinalspange" in the sense of Wintrebert. The caudal elongation of the dental lamina of the vomer is correlated with the outgrowth of the vomerine bar.

Cranial Bones: Lateral View
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...

Changes in the Appendicular Skeleton with Age
Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...
Sutures of the Skull
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...
