Answer 2

Answer :-

Bones are living tissues which serve as the main components of the Skeletal system.

Extra Information :-

• The matrix of bone consists of an organic compound called "Ossein" along with "Collagen fibres".

• The major component of bone is Hydrated Calcium Phosphate.

• Bone consists of Fluorides, Sulphates, Magnesium salts and some Carbonates.

• "Collagen Protien" makes about 33% of the bone.

• During ageing, the proportion of Protien in a bone decreases which as a result, makes the bone brittle.

• Bones are almost completely covered by a dense, white fibrous sheath known as "Periostium".

• The medullary or marrow cavity of a bone is lined with "Endosteum".
