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

Osteoblasts’ function is to ____

A	signal to osteocytes when to secrete more bone matrix
B	mature into osteoclasts
C	break down old bone matrix
D	secrete bone matrix

Explanation:

Detailed explanation-1: -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-2: -This is false. The type on bone cell that secretes bone matrix in order to build more bone tissue is the osteoblast. Osteoclasts do the opposite function of osteoblasts. Osteoclasts break down matrix by releasing large amounts of protons.

Detailed explanation-3: -Osteoblasts secrete a range of proteins: Type 1 collagen, osteocalcin, osteonectin and osteopontin. In addition, a battery of locally active chemical factors including osteoclast stimulating factor are produced.
