Anatomy of the Lungs and Pleura

Ninja Nerds!

In this lecture, Professor Zach Murphy presents on the anatomy of the Lungs and Pleura. The session begins with an in-depth digital presentation using professional anatomical illustrations to explore the structure and relationships of the lungs, including the right and left lung lobes, fissures, and surfaces. We identify key landmarks such as the apex, base, hilum, and root of the lungs, while emphasizing the differences between the right and left lungs, including the presence of the cardiac notch and lingula.

We then examine the pleura in detail, discussing the parietal and visceral layers, the pleural cavity, and the pleural recesses—highlighting the costodiaphragmatic and costomediastinal recesses and their clinical significance in thoracentesis and drainage of pleural effusions.

The lecture continues with an examination of the bronchopulmonary segments, illustrating their surgical and clinical relevance, particularly in segmental lung resections and localized disease processes, such as pneumonia and bronchiectasis.

We also cover the vascular supply and lymphatic drainage of the lungs, emphasizing the pulmonary arteries, veins, and bronchial vessels, as well as the superficial and deep lymphatic plexuses. Autonomic innervation of the lungs is reviewed to explain bronchoconstriction, bronchodilation, and visceral pain referral patterns.

To conclude, we transition to @Anatomage where we visualize the lungs and pleura in real digital cadaveric images, reinforcing the spatial and three-dimensional relationships between the lungs, pleura, mediastinum, and diaphragm. This portion integrates anatomical understanding with clinical application to enhance mastery of thoracic anatomy.Enjoy the lecture, and please support us below!
