The cartilages of the trachea and bronchi arc also hyaline. Structure,—Like other cartilages it is composed of cells imbedded in a matrix. The cells, which con- tain a nucleus with nucleoli, are irregular in shape, and generally grouped together in patches (fig. 39). The patches are of various shapes and sizes, and placed at unequal distances apart. They generally appear flattened near the free surface of the mass of cartilage in which they are placed, and more or less perpendicular to the surface in the more-deeply seated portions. The matrix of hyaline cartilage pearance like that of ground glass, and in man and the higher 2*# 0 Fig-. 39. — Ordinary hyaline cartilage from trachea of a child.
