Perichondrium vs. Periosteum: What's the Difference?
Perichondrium is a dense layer of connective tissue surrounding cartilage, while periosteum is a membrane covering bones, except at joint surfaces.
The perichondrium surrounds and protects cartilage, aiding in its growth and repair. The periosteum covers bones, providing a surface for muscle attachment and facilitating bone growth and repair.
Both the perichondrium and periosteum consist of dense connective tissue, but the periosteum has a fibrous outer layer and a cellular inner layer, which the perichondrium lacks.
The perichondrium has a rich blood supply, essential for cartilage nutrition and growth. The periosteum is highly vascularized and innervated, playing a key role in pain sensation in bones.
Perichondrium contributes to cartilage growth and is essential during the repair of cartilage injuries. The periosteum is crucial for bone growth, especially during the healing of fractures.
The perichondrium contains cells that can differentiate into chondrocytes, the cells of cartilage. The periosteum contains osteoblasts and osteoclasts, crucial for bone formation and remodeling.
