In some places, especi- ally in articular cartilage (Till- manns, Baber), bundles of fine conne ctive tissue fibrils may be noticed in the hyaline ground sub- stance. 57. In some cartilages, the protoplasm of the cell becomes filled with fat globules (Fig. 30c). This fact may be observed in many normal cartilages; sometimes the fat globules become confluent into one large drop, and then the cell has the appearance of a fat cell. In age, disease, and defi- cient nutrition, lime salts are deposited in the ground substance, beginning from the circumference of the cells. The lime matter appears in the shape of opaque granules, or irregular or angular clumps. The ground sub- stance thereby loses its transparency, becomes opaque in transmitted, white in reflected, light, and, of course, very hard and brittle. This process is the calcification of cartilage. It is also met with in cartilage that is to be From a Preparation of Sternal Cartilage of Newt. The lacunas, containing the cartilage cells, anastomose by fine Fig. 30C—Three Car- tilage Cells filled with Fat Droplets.
