Periosteum vs. Endosteum: What's the Difference?

Edited by Sumera Saeed || By Sara Rehman || Published on January 22, 2024
Periosteum is a dense, fibrous membrane covering the outer surface of bones; endosteum lines the inner surface of bone cavities.

Key Differences

Periosteum envelops the bone's outer surface, providing a surface for muscle attachment and bone growth. Endosteum lines the inner cavity, playing a role in bone growth and repair from the inside.

The periosteum contains blood vessels and nerves, contributing to bone health and pain sensation. Endosteum is a thin layer, less vascularized, involved mainly in bone remodeling and marrow activities.

Periosteum has two layers: a fibrous outer layer and a cellular inner layer. Endosteum is a single, thin layer of connective tissue.

Injuries to the periosteum can affect bone growth and lead to pain due to its nerve supply. Damage to the endosteum can disrupt bone marrow and internal bone remodeling.
