Learning Outcomes

There are three primary types of bones in the skeletal system. These bones include the flat bones, the long bones, and the irregular bones. Long bones are dense, hard bones that provide mobility, strength, and structure. A long bone has a shaft and two ends. The femur (i.e., thigh bone) is an example of this type of bone.
