Document Summary
Articular cartilage at the ends of bones protects the periosteum. Organic: makes it flexible and resilient; made up of water. Makes up 30% of its body weight. Inorganic: makes it hard and rigid; made up of calcium and phosphate. Makes up about 70% of its body weight *know this is more dont need to. Ii. figure 2. 2 and 2. 3- picture of femur know % Medial and lateral trabecular systems are important in improving strength of the bone for wb properties and for abductor and adductor moments. Osteoporosis causes the bone to be more porous. Spontaneous fracture- when weak bone fractures spontaneously without any form of trauma (ex falling); can be due to cancer of the bone or severe osteoporosis structure. The combination of both organic and inorganic materials that make up the bone make it more strong than if bone was made up by solely one material or the other load deformation curve (figure 2. 6)
