Ribs are long, curved bones that form the ribcage, which protects the organs in the chest cavity, such as the heart and lungs. Humans have 12 pairs of ribs, with the first seven pairs known as true ribs because they are attached directly to the sternum (breastbone) by cartilage. The remaining five pairs are known as false ribs because they are either attached indirectly to the sternum or not at all. Ribs play a crucial role in protecting the vital organs and providing support for the upper body.

Definition:
Ribs are a series of curved, bony structures that form the thoracic cage, which protects the heart, lungs, and other vital organs.
Structure:
- True ribs (ribs 1-7): Directly connected to the sternum (breastbone) by costal cartilages.
- False ribs (ribs 8-10): Indirectly connect to the sternum through costal cartilage.
- Floating ribs (ribs 11-12): Not connected to the sternum at all.
Features:
- Head: Articulates with the vertebral body posteriorly.
- Neck: Slender and connects the head to the body.
- Body: Flattened and curved, forming the main part of the rib.
- Tuberosity: A projection near the head where the costal cartilage attaches.
- Angle: A sharp bend in the body of the rib (in ribs 2-10).
- Costal groove: A groove on the inferior surface of the rib that houses intercostal vessels and nerves.
Types of Ribs:
- Typical ribs (ribs 3-9): Have the full complement of features described above.
- Atypical ribs:
- First rib: Flat and has a groove for the subclavian artery and vein.
- Second rib: Has a shallow notch for the attachment of the serratus anterior muscle.
- Last 3 ribs: Are shorter and lack some of the features of typical ribs.
Functions:
- Protection: Shield the thoracic organs from injury.
- Support: Provide structural support for the thoracic cavity.
- Respiration: Allow for the expansion and contraction of the chest during breathing.
- Muscle attachment: Serve as insertion points for intercostal muscles, which are responsible for breathing.
