As well, proteins, minerals and vitamins make up the bone. Bones have several parts, but are manily made out of calcium deposits. It takes around 20 years for our bones to completely harden. The building of bones happens throughtout our lives. We are born with about 300 soft bones. During childhood and adolescence, the cartilage grows and is slowly replaced by hard bone. Some of these bones later fuse together, so that the adult skeleton has 206 bones. Bones are composed of two types of tissue. 1. A hard outer layer called cortical (compact) bone, which is strong, dense and tough.
2. A spongy inner layer called trabecular (cancellous) bone. This network of trabeculae is lighter and less dense than compact bone.
Osteoporosis makes your bones weak and more likely to break. Anyone can develop osteoporosis, but it is common in older women. As many as half of all women and a quarter of men older than 50 will break a bone due to osteoporosis.
Osteoporosis is a condition that causes weakening of the bones in your body. Also called "brittle bone disease," osteoporosis increases your chance of sustaining a broken bone. Broken bones can cause significant problems, especially when a spine fracture or broken hip occurs. Because of these concerns, all people should understand their chance of developing osteoporosis, and if they need steps to prevent the development or progression of osteoporosis.
