MICROANATOMY

Detailed explanation-1: -Bone matrix is a composite consisting of organic and inorganic components. The organic matrix makes up  20% of bone wet weight and is comprised primarily of type I collagen which gives bone its flexibility.

Detailed explanation-2: -Bone matrix (also known as osteoid) consists of about 33% organic matter (mostly Type I collagen) and 67% inorganic matter (calcium phosphate, mostly hydroxyapatite crystals). The osteoblasts occur as simple, epithelial-like layer at the developing bone surface.

Detailed explanation-3: -Bone tissues consist of collagen fibers and ground substance containing calcium, magnesium, and phosphate ions that chemically combine and harden into a mineral, hydroxyapatite. The combination of hard mineral and flexible collagen makes bone harder than cartilage without being brittle.
