Study Notes
Surface Marking of Pleura (Parietal)
- Cervical pleura: Represented by a curved line, approximately 2.5 cm above the clavicle.
- Anterior margin: Extends from the sternoclavicular joint to the sternal angle, vertically downwards to the xiphisternal point.
- Left side: Follows the same path upwards to the 4th costal cartilage level and then curves downwards to the 6th costal cartilage.
- Posterior margin: Located 2 cm lateral to the 12th thoracic vertebra, extending laterally to the 4th cervical vertebra.
- Inferior margin: Crosses the 8th rib in the midclavicular line or the 10th rib in the midaxillary line.
Surface Marking of Pleura (Visceral)
- Apex: 2.5 cm above the medial 2/3 clavicle.
- Anterior border: Right side corresponds closely with the costomediastinal line. This border is obtained by joining the sternoclavicular joint, sternal angle, medial plane, and just above the xiphisternal joint.
- Left side: Corresponds to the costomediastinal line up to the 4th costal cartilage.
- Inferior part: Represents the cardiac notch. This part passes laterally 3.5 cm from the sternal margin and curves down medially to reach the 6th costal cartilage.
- Lower border: Crosses the 6th rib in the midclavicular line and the 8th rib in the midaxillary line. The cardiac notch is dull on percussion.
