Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

The “new bone” material laid down by osteoblast is called the:

A	Osteocyte
B	Bone matrix
C	Articular cartilage
D	Osteon

Explanation:

Detailed explanation-1: -Osteoblasts are the cells that synthesize bone matrix proteins and are active in bone matrix mineralization. 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).

Detailed explanation-2: -The osteoblasts secrete the organic matrix, which are dense collagen layers that alternate parallel and orthogonal to the axis of stress loading. Into this matrix is deposited extremely dense hydroxyapatite-based mineral driven by both active and passive transport and pH control.

Detailed explanation-3: -Osteoblasts are cells responsible for the secretion and deposition of bone morphogenetic proteins (BMPs) into the extracellular matrix during bone formation.
