What are the bones made up of?
Bones are made up of a framework of a protein called collagen, with a mineral called calcium phosphate that makes the framework hard and strong. Bones store calcium and release some into the bloodstream when it’s needed by other parts of the body.
Is bone tissue alive?
Bones are living tissue which have their own blood vessels and are made of various cells, proteins, minerals and vitamins. This structure enables them to grow, transform and repair themselves throughout life.
What composes most of the mass of bones?
Bone material properties * The mineral component is composed of hydroxyapatite, which is an insoluble salt of calcium and phosphorus. About 65\% of adult bone mass is hydroxyapatite. * Bone also contains small amounts of magnesium, sodium, and bicarbonate. * Water comprises approximately 25\% of adult bone mass.
Are bones solid?
The bones in the skeleton are not all solid. The outside cortical bone is solid bone with only a few small canals.

What is matrix in bone?
The bone matrix is that part of the bone tissue and forms most of the mass of the bone. It is comprised of organic and inorganic substances. The organic component of the bone matrix includes the collagen and ground substance whereas the inorganic component is the inorganic bone salts, mainly the hydroxyapatite.
