cartilage (gristle). In this the formative cells (the cartilage
corpuscles) are enjellied in a clear structureless matrix (Figure XII.),
consisting entirely of organic compounds accumulated by their
activity. Immediately round the cell lies a capsule of newer material.
Some of the cells have recently divided (1); others have done so less
recently, and there has been time for the interpolation of matrix, as
at 2. In this way the tissue grows and is repaired. A thin layer of
connective tissue (see below), the perichondrium, clothes the
cartilaginous structure.
