The transition from one form of tissue to the other can be seen in the adult synovial cavities, and is important as additional evidence of the slight real difference between mesenchyma and epithelium. I know no observations on the development of the arachnoid spaces. Synovial and Bursal Cavities.--The development of the synovial cavities has been studied by Hagen-Torn, 82.1. Between the cartilages of the limbs there is left undifferentiated mesenchyma, which very early acquires blood-vessels and shows later an increased vascularity. The formation of the cavity begins in the centre between the cartilages, and is first indicated by the tissue becoming less dense there (rabbit embryos l!(-20 mm.); some of the central cells undergo a mucoid degeneration and disappear, others become spindle-shaped and change into cartilage cells, with the result that the ends of the skeletal cartilages are now separated from one another only by a slight space. At the sides of the cavity the mesenchyma forms the synovial membrane, which is merely very vascular, fibrillar connective tissue; upon the synovial surface patches of endothelium are developed. Villi, if formed at all, appear in later stages and always at the sides of the cavity by the synovial membrane proper. Membranes.--The development of the various membranes and special mesenchymal layers, such as the submucosa, dermis, etc., is considered in connection with the various organs, to which they belong. There is one general feature which may be mentioned here, namely, the so-called basement membranes. By this term is now generally understood the layers of endothelioid cells found immediately underneath various epithelia: for instance, under the ...
