    I network of branched cells \ but in the adult state he reticulum itself possesses no nuclei. Those found )n it do not form an essential part of it. (2) The neuroglia of Yirchow is a dense network )f very fine homogeneous fibrils which form the sup- porting tissue for the nervous elements in the central lervous system. These fibrils are supposed to be elastic fibres (Gerlach). Embedded in the network of hese fibres are found branched nucleated flattened iell plates, which are the proper connective tissue cells. (3) Gelatinous tissue. This occurs chiefly in }he embryo, being the unripe state of fibrous jionnective tissue. It consists of spindle-shaped or branched connective tissue cells, separated from one mother by a homogeneous transparent mucoid sub- stance. It is met with in the umbilical cord and in johe cavity of the middle ear of the embryo, and in :he places where fibrous connective tissue is to be developed. After birth it is found in the tissue of he pulp of the teeth, and in some places as precursor Df fat tissue, i CHAPTER YI. CARTILAGE. 54. Cartilage consists of a firm ground substance which jdelds chondrin^ and of cells embedded in it. Most cartilages (except on the articulating surface) are covered on their free surface with a membrane |Df fibrous connective tissue with a few elastic fibrils. This membrane is supplied with blood-vessels, lym- phatics, and nerves, and is of essential importance for the life and growth of the cartilage. This is the peri- chondrium. There are three varieties of cartilage.
