As we age, the amount of collagen in the extracellular matrix of bone decreases and bones become more brittle. Which osseous tissue cell secretes collagen?

Osteoblasts

Explanation:

Osteoblasts are pulled in to the reabsorbed zone by bone-determined development factors and perhaps by compound signs discharged by dead osteoclasts. Osteoblast enlistment is invigorated by development components, PTH, and calcitriol. The osteoblasts at that point emit progressive layers of the bone-shaping protein collagen (prevalently type I collagen) together with osteocalcin and different proteinsThese cells likewise speak with each other and with osteocytes by hole intersections because these cells are bone forming cellsHence, the right answer is "osteoblasts cell secretes collagen"
