Bone is a metabolically active connective tissue that provides structural support, facilitates movement, and protects [[Vital Organs|vital organs]]. Bone is composed of an [[Extracellular Matrix|extracellular matrix]] and bone cells (osteocytes).El Sayed SA, Nezwek TA, Varacallo M.

Available from:https://www.ncbi.nlm.nih.gov/books/NBK441968/ (last accessed 10.2.2020) Under the right conditions, bone tissue undergoes a process of mineralisation, and is hardened by deposited calcium. Bone is hard and many of its functions depend on that characteristic hardness.Opentextbc.ca. (2018). ''6.3 Bone Structure – Anatomy and Physiology''. [online] Available at:
https://opentextbc.ca/anatomyandphysiology/chapter/6-3-bone-structure/ The adult human skeleton is composed of 206 bones. At birth, there are approximately 270 bones, with the final adult count decreasing as a portion of these bones fuse during phases of skeletal growth and maturation. During life, bone is constantly remodelling with most of the adult skeleton being replaced about every 10 years.Office of the Surgeon General (US.
