ossified

Examples of ossified in the following topics:

• The Hyoid Bone

  • The hyoid ossifies towards the end of fetal development, commencing in the greater cornua before completing in the body shortly after birth.
  • The greater cornua and body are initially connected by fibrous material although this ossifies towards middle age.

• Sutures

  • In old age the cranial sutures may ossify completely, reducing the amount of elasticity present in the skull.

• Growth of Bone

  • On the diaphyseal side, cartilage is ossified, allowing the diaphysis to grow in length.
  • It is considered a part of the growth plate: the part of the bone that grows during childhood, which, as it grows, ossifies near the diaphysis and the epiphyses.

• Sutures

  • At some sutures, the connective tissue will ossify and be converted into bone, causing the adjacent bones to fuse to each other.
  • Late in life, the sagittal, coronal, and lambdoid sutures of the skull will begin to ossify and fuse, causing the suture line to gradually disappear.

• Bone Remodeling and Repair

  • This is similar to the endochondral formation of bone when cartilage becomes ossified; osteoblasts, osteoclasts, and bone matrix are present.

• Gnathostomes: Jawed Fishes

  • Nearly all bony fish have an ossified skeleton with specialized bone cells (osteocytes) that produce and maintain a calcium phosphate matrix.

• Structure, Type, and Location of Cartilage

  • In the embryo, bones form first as hyaline cartilage before ossifying as development progresses.
