Question

Matrix of bone is characterised by the presence of
(1) Calcium phosphate, osteocytes and collagen
fibres
(2) Calcium carbonate, lacunae and chondrocytes
(3) Ossein and collagen fibres only
(4) Calcium pectate, ossein and collagen fibres​

Answer 1

Answer:

.......... ................ .......

Answer 2

Calcium phosphate, osteocytes, and collagen (option A) is the right answer.

• The matrix of bone is the part of bone tissue that forms most of the mass of the bone in a body.
• The matrix of bone consists of living cells present inside it.

• The matrix consists of organic and inorganic components.
• The organic component in the matrix of bone is type 1 collagen, it is almost 90%of the organic components.
• Collagen assembles into fibers that form the structure of bone.
• Calcium phosphate helps in bone regeneration by activation of osteoblasts and osteoclasts.
• Osteocytes have a regulatory role in process of bone remodeling.

        Hence option A is correct
