cancellous

It would seem that the first change is one of congestion of the vessels of the bone's cancellous tissue.

Bone may be compact, or loose and spongy in character, when it is known as cancellous bone.

The tympanic is not fused to the periotic and has a small bulla not filled with cancellous bone.

These horn cores are formed internally of cancellous bone, and on them the true epidermal horns are borne.

The spongy or cancellous osteoma is really an ossified chondroma, and is met with at the ends of the long bones (Fig. 52).
