Copyright © 2004 Pearson Education, Inc., publishing as Benjamin Cummings Medical history Weight Gender Body size Muscle mass Age Important Variation in the Skeletal System
Copyright © 2004 Pearson Education, Inc., publishing as Benjamin Cummings Begin about age one Continue throughout life Age related changes in skeletal system
Copyright © 2004 Pearson Education, Inc., publishing as Benjamin Cummings You should now be familiar with: The bones of the pectoral girdle and upper limbs, their functions and their features. The bones of the pelvic girdle and lower limbs, their functions and their features. The similarities and differences between the male and female skeleton and pelvic structure. How the skeleton can reveal significant information about the individual. The effect of aging on the skeleton.
