Internal rotation: This reaches a greater degree when the hip joint also rotates in. A good bridge, where the feet and hands are distant by one forearm, requires almost all the joints to be extended. Flexion: Just as is the case in the elbow, muscles can impede the flexion. The cortical bone gives bone its smooth, white, and solid appearance, and accounts for 80% of the total bone mass of an adult human skeleton. Calcium salts give bone hardness, and provides significant flexibility ossein. The process of bone repair includes these steps: a: Fracture hematoma forms b: Bone is remodeled c: Fibrocartilaginous callus forms d: Bony callus forms The correct chronological order for these steps is a. a - c - d – b 15. Its range of movement is quite limited, but, because we always use it allied to other stretches, it often looks as if it allowed considerable motion. Long bones are mainly made of cortical bone, favoring rigidity over flexibility, whereas mainly trabecular vertebrae can absorb more energy by deforming more before breaking.
