Definitions of OSSIFICATION, POINTS OF
Sort: Oldest first
Puncta seu Nuclei ossificationis, Nuclei ossei, are the points where the ossification of a bone commences, whence it extends to other parts. Almost all the bones present a greater or less number of points of ossification. Besides the natural ossification, which we observe in the foetus and in the first periods of life, there are also accidental ossifications, such as those frequently remarked after the inflammation of serous membranes, in the parietes of arteries, and to which the terms Osthexia, Incrustation and Petrifaction have, sometimes, been applied.
