Ossification \Os`si*fi*ca"tion\, n. [Cf. F. ossification. See
   {Ossify}.]
   1. (Physiol.) The formation of bone; the process, in the
      growth of an animal, by which inorganic material (mainly
      lime salts) is deposited in cartilage or membrane, forming
      bony tissue; ostosis.

   Note: Besides the natural ossification of growing tissue,
         there is the so-called accidental ossification which
         sometimes follows certain abnormal conditions, as in
         the ossification of an artery.

   2. The state of being changed into a bony substance; also, a
      mass or point of ossified tissue.
