perichondrium

[‚per·ə′kän·drē·əm]
(anatomy)
The fibrous connective tissue covering cartilage, except at joints.

Perichondrium

 

connective tissue that invests cartilage. Perichondrial cells become differentiated into cartilaginous cells at the same time as the dense homogeneous basic matter of the cartilage forms. In young organisms the perichondrium is converted to periosteum in the process of the development of bone from cartilage.
