Flashcards
Pleurisy pain referral
Pleurisy pain referral
Pain from pleurisy (inflammation of the pleura) is felt in areas distant from the source due to shared nerve innervation. This is called referred pain.
Parietal pleura innervation
Parietal pleura innervation
The parietal pleura is supplied by nerves that innervate the chest wall (intercostal nerves) and diaphragm (phrenic nerve).
Cervical pleura location
Cervical pleura location
The cervical pleura covers the apex (top) of the lung and is attached to the suprapleural membrane.

Study Notes
Pleurisy and Pleura Anatomy
- Pleurisy Pain Referral: Referred pain from pleurisy (inflammation of the pleura) to the thoracic and abdominal walls, and shoulder tip, is due to somatic innervation of the parietal pleura by intercostal and phrenic nerves.
- Cervical Pleura: Covers the lung apex and is superiorly bounded by the suprapleural membrane.
- Parietal Pleura Blood Supply: Primarily supplied by branches of thoracic wall arteries such as intercostal and phrenic arteries, not bronchial arteries.
- Mediastinal Pleura: Covers the mediastinum, positioned within the thoracic cavity and interacting with mediastinal structures.
- Visceral vs. Parietal Pleura: The key distinction is that the visceral pleura intimately adheres to the lung's surface and fissures, while the parietal pleura lines the chest wall and diaphragm.
- Suprapleural Membrane Function: Forms a boundary for the cervical pleura at the apex of the lung.
