<prompt> Primary metabolic bone disorder in scurvy is ?Decreased mineralizationDecreased osteoid matrix formationIncreased bone resorptionDecreased bone mass with normal mineralization and osteoid formation  <response>: Ans. is b i.e., Decreased osteoid matrixo Collagen is a component of osteoid protein matrix.o Collagen synthesis is deficient in scurvy; therefore, osteoid formation is defective.o On the other hand, in rickets osteoid formation is normal, but mineralization Calcification of osteoid is defective.
