This latter discharge became more infrequent, the bone being replaced by cartilaginous substance.
They have a soft and elastic consistency, and are usually composed of a hyaline or reticular cartilaginousaxis covered with connective or adipose tissue and skin bearing fine hairs; sometimes both cartilage and fat are absent.
The point of junction was about the sterno-siphoid angle, a cartilaginous band extending from sternum to sternum.
The cartilaginous ends of the bones grow rapidly, but ossification does not keep pace with it.
In other joints the bones are bound together by dense, cartilaginous structures, admitting of only limited motion, such as the union of the small bones at the back part of the knee and hock (metacarpal and metatarsal).
