growth/size/body

decreased body weight ( J:178743 )

skeleton

decreased bone mineral content ( J:178743 )

• decreased bone mineral content

• lower cortical volumetric tissue mineral content

increased bone mineral density ( J:178743 )

• Background Sensitivity: bone mineral density is higher on the mixed BALB/cByJ and C57BL/6 background compared to F1 crosses to FVB/NJ, or C3H/HeJ but lower compared to F1 crosses to A/J

increased volumetric bone mineral density ( J:178743 )

• cortical volumetric tissue mineral density (vTMD) is elevated in the femur

decreased bone volume ( J:178743 )

decreased compact bone area ( J:178743 )

decreased compact bone thickness ( J:178743 )

decreased bone trabecula number ( J:178743 )

• fewer and more widely spaced trabeculae

decreased bone strength ( J:178743 )

• femurs are weaker and more brittle
