2.1 Bone metabolism and structure
Healthy bones provide:
- a strong skeletal structure but to allow efficient movement, weight is minimised
- a site for haematopoiesis (the production of blood cells by the bone marrow)
- a reservoir of calcium
Bone is not a single structure, but has 2 subtypes
Cortical bone
Cortical bone is dense, made of smooth layers of bone tissue and nourished by blood vessels.
Trabecular bone
Trabecular bone consists of a honeycomb-like network of interconnecting bone tissue, interspersed with spaces filled with bone marrow.
