perichondrium

Examples of perichondrium in the following topics:

• Development of the Skeleton

  • The perichondrium becomes the periosteum that contains a layer of undifferentiated cells (osteoprogenitor cells) which later become osteoblasts.
  • The hypertrophic chondrocytes (before apoptosis) secrete Vascular Endothelial Cell Growth Factor that induces the sprouting of blood vessels from the perichondrium.

• Structure, Type, and Location of Cartilage

  • The cartilage fibrous sheath is called the perichondrium.
  • Hyaline cartilage is covered externally by a fibrous membrane, called the perichondrium, except at the articular ends of bones; it also occurs under the skin (for instance, ears and nose).

• Supply of Blood and Nerves to Bone

  • Growth cartilage receives its blood supply from both sources and also from an anastamotic collar in the adjoining perichondrium.

• Embryonic and Fetal Bone Formation

  • The perichondrium becomes the periosteum.
