dense irregular connective tissue that surrounds the
cartilage of developing bone. It consists of two separate layers: an outer fibrous layer and inner
chondrogenic layer. The fibrous layer contains
fibroblasts, which produce
collagenous fibres. The chondrogenic layer remains undifferentiated and can form
chondroblasts. Perichondrium can be found around the perimeter of
elastic cartilage and
hyaline cartilage.
Perichondrium is a type of irregular collagenous ordinary connective tissue, and also functions in the growth and repair of cartilage. Perichondrium contains
type I collagen and
type XII collagen.
