A flat bone is one of the types of bones classified by shape.
Flat bones have a thin shape and, in some cases, provide mechanical protection to soft tissues beneath or enclosed by the flat bone e.g. cranial bones that protect the brain.
Flat bones also have extensive surfaces for muscle attachments e.g. scapulae (shoulder) bones.
- Cranial bones (protecting the brain) e.g.
- Sternum (protecting organs in the thorax)
- Ribs (protecting organs in the thorax)
- Scapulae (shoulder blades).
