Cancellous Bone vs. Cortical Bone: What's the Difference?

Edited by Huma Saeed || By Sumera Saeed || Published on February 2, 2024
Cancellous bone s spongy, porous, found inside bones. Cortical bone is dense, compact, forms the outer layer of bones.

Key Differences

Cancellous bone, also known as trabecular or spongy bone, is characterized by its porous, honeycomb-like structure. In contrast, cortical bone, also referred to as compact bone, is dense and forms the hard outer shell of bones.

The main function of cancellous bone is to absorb shock and reduce the weight of bones, making them lighter. Cortical bone, on the other hand, provides strength and structure, protecting and supporting the body.

Located mostly in the ends of long bones and in the pelvis, spine, and skull, cancellous bone contains red bone marrow, where blood cells are produced. Cortical bone is found throughout the body, making up approximately 80% of skeletal mass.

Cancellous bone has a high surface area to mass ratio, which facilitates the exchange of calcium ions and other substances. Cortical bone, with its lower surface area to mass ratio, is less involved in metabolic processes.

The architecture of cancellous bone changes throughout life, adapting to stress and trauma. Cortical bone also changes over time, but it is more resistant to bending and twisting forces.
