Question

Aging affects bone in two ways. First, the tensile strength of bone decreases due to a reduced rate of ____________ by osteoblasts. Consequently, the relative amount of inorganic minerals in the bone matrix ____________ . The bones of the skeleton become ____________ and susceptable to ____________ . Second, bone ____________ (loses calcium and other minerals). The bones of the skeleton become thinner and weaker, resulting in insufficient ____________ , a condition called ____________ .

Answer 1

Answer:

Protein synthesis, increases, brittle, fracture, dimineralisation, ossification, osteopenia

Explanation:

Aging affects bone in two ways. First, the tensile strength of bone decreases due to a reduced rate of protein synthesis by osteoblasts. Consequently, the relative amount of inorganic minerals in the bone matrix increases . The bones of the skeleton become brittle and susceptable to fracture . Second, bone loses calcium and other minerals(dimeneralisation). The bones of the skeleton become thinner and weaker, resulting in insufficient ossification, a condition called osteopenia.

Answer 2

Answer:

a. Protein synthesis

b. Increases

c. Brittle

d. Fracture

e. Demineralizes

f. Ossification

g. Osteopenia

Explanation:

Aging affects bone in two ways. First, the tensile strength of bone decreases due to a reduced rate of PROTEIN SYNTHESIS by osteoblasts. Consequently, the relative amount of inorganic minerals in the bone matrix INCREASES The bones of the skeleton become BRITTLE and susceptable to FRACTURE. Second, bone DEMINERALIZES (loses calcium and other minerals). The bones of the skeleton become thinner and weaker, resulting in insufficient OSSIFICATION , a condition called OSTEOPENIA

Aging occurs in people as they grow older due to a reduction in the density of their bones. The mineral content of the bones tend to decrease thereby making the bones brittle and more susceptible to fracture( breaking of the bones)
