• Bones connect and fuse together as a person ages
• Joints: location where bones meet
– Cartilage: wraps around bones for protection
– Ligaments: bands of tissue connecting together two or more bones
– Tendons: connect muscles to bone

• Children build bones at a faster rate than bones being broken down. Thus bones increase in size
(growth)
• After the age of 30, bones begin to deteriorate faster than they are being built
– Excising can slow deterioration
• People with osteoporosis are at risk of bone breakage due to loss of calcium
• The number of bones and their conditions can tell investigators about a person’s age, health, and whether the person had enough calcium
