Several bones in the human body are classified as flat bones. These bones share a similar structure, consisting of two thin layers of compact bone that sandwich a layer of cancellous bone, where red bone marrow is found. According to our reference, here is a list of flat bones:
List of Flat Bones
| Bone | Location |
|---|---|
| Occipital | Back of the skull |
| Parietal | Sides and top of the skull |
| Frontal | Forehead |
| Nasal | Bridge of the nose |
| Lacrimal | Inner eye socket |
| Vomer | Nasal cavity |
| Sternum | Breastbone |
| Ribs | Chest cage |
| Scapulae | Shoulder blades |
These flat bones provide protection for vital organs or offer broad surfaces for muscle attachment.
Characteristics of Flat Bones
- Structure: Flat bones are characterized by two thin layers of compact bone with cancellous bone in between.
- Red Bone Marrow: This type of bone is crucial as it houses red bone marrow, which is responsible for blood cell production.
- Protection: These bones protect underlying tissues and organs. For example, the skull bones protect the brain, and the ribs protect the lungs and heart.
- Muscle Attachment: Flat bones provide a broad surface for muscle attachments.
In conclusion, the question "What bone is flat?" has multiple answers. The reference information details that bones such as the occipital, parietal, frontal, nasal, lacrimal, vomer, sternum, ribs, and scapulae are all classified as flat bones.
