Typical rib

A curved plate that links the spine to the chest wall

ThoraxSkeletal system

High-yield

The groove near the lower edge shelters the main intercostal bundle. Its usual superior-to-inferior order is vein, artery, then nerve.

Overview

Ribs 3–9 show the usual head, neck, tubercle and curved shaft pattern. The head and tubercle attach the rib to the vertebral column, while the anterior end continues into costal cartilage.

Reference facts

Flat bone
Key landmarks
Head; Neck; Tubercle; Rib angle; Curved shaft; Costal groove
Articulations
Head with adjacent vertebral bodies in a typical rib; tubercle with the same-numbered vertebra's transverse process; anterior end with costal cartilage

Clinical correlation

A rib fracture can injure nearby vessels, pleura or lung. Smaller collateral vessels also occupy the rib space, so knowing the main bundle's position does not make a rib border a universally safe procedural route.
