Perichondrium vs. Periosteum: What's the Difference?

Edited by Sumera Saeed || By Sawaira Riaz || Published on December 26, 2023
Perichondrium is a dense layer of connective tissue surrounding cartilage, while periosteum is a membrane covering bones, except at joint surfaces.

Key Differences

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.
