Which pathological bone outcome occurs when osteoblast deposition lags significantly?

A)Increased bone resorption and density loss
B)Cancellous fracture resistance maintains equilibrium
C)Accelerated osteoblast differentiation maintains density
D)Osteocyte induced bone formation upregulates density

💡 Explanation

Decreased osteoblast activity leads to reduced bone matrix production, initiating bone resorption via 'bone remodeling'. Because resorption outpaces deposition, bone density decreases; therefore, osteoporosis risk increases, rather than density increasing or maintaining homeostasis, or fracture resistance compensating.
