(Return to Courseware Index) Pleural Cavities & Lung LAB MANUAL |Topic and Text Reference | Learning Objectives | Special Instructions | Clinical Exercises | Key Structures TOPIC AND TEXT REFERENCE: PLEURAL CAVITIES AND LUNG PP. 48-52 LEARNING OBJECTIVES: Understand the boundaries of the pleural cavity. Learn the difference between parietal and visceral pleura. Learn the different parts of the parietal pleura. Learn the surface anatomy of the lung: fissures and lobes. Identify the structures that have a direct relationship to the lungs. Learn the key differences between the right and left lung. Learn the dual blood supply to the lungs. SPECIAL INSTRUCTIONS FOR LAB TODAY: Pg. 49: Be aware that as you remove the rib cage, the sternocostal parietal pleura often remains attached to its inner surface. Pg. 50: The faculty members will circulate with scalpels and supervise as you cut through the root of the lungs to remove them. • Pg 50: Look for the contact impressions on the lungs. These vary from cadaver to cadaver (like everything else!). So if they are not easily seen on yours, look at a neighboring cadaver and the lung models in Room 106. Pg. 51: Do NOT cut into the lung and follow the segmental bronchi. You "can" familiarize yourself with the bronchopulmonary segments by using your textbook. CLINICAL CORRELATIONS AND EXERCISES: 1.Where does one place the needle to remove liquid from the pleural cavity? 2. Where does one place the needle to remove air from the pleural cavity? 3. Make a list of the layers that the needle must pass through to enter the pleural cavity? Which of these layers are somatically innervated and which are viscerally innervated? 4. Why do objects become lodged in the right bronchus with a greater frequency than the left? 5. Why is the lung apex vulnerable to injury? KEY STRUCTURES: You should be able to identify in a cadaver all the structures listed under key words unless they have an asterisk. structure Netter's Gold Standard structure Netter's Gold Standard Arteries     Nerves     intercostal artery N1   intercostal nerve N1   internal thoracic artery N1   recurrent laryngeal nerve, left N1   pericardiacophrenic artery N1 G1 phrenic nerve N1   pulmonary artery N1 G1 Pleurae     pulmonary trunk N1   costal pleura N1   Lungs     cupula pleura N1   hilus of lung N1   diaphragmatic pleura N1   Lungs - fissures     mediastinal pleura N1   horizontal fissure N1 G1 pleural cavity     oblique fissure N1 G1 (left) | G2 (right) visceral pleura N1   Lungs - impressions - right lung     Recesses     aortic arch impression   G1 costodiaphragmatic recess N1   arch of the azygos vein impression N1 G1 Veins     cardiac (right atrium) impression N1 G1 intercostal vein N1   Lungs - impressions - left lung     internal thoracic vein N1   arch of the aorta impression N1   pulmonary vein N1   ascending aorta impression     superior vena cava N1   descending aorta impression N1   Other structures     groove for the esophagus N1   bronchus N1   cardiac (left ventricle) impression N1   cardiac notch N1   Lungs - roots     endothoracic fascia     left lung N1   fibrous pericardium N1   right lung N1   ligamentum arteriosum N1   Muscles     oblique pericardial sinus N1   external intercostal muscle N1   parietal layer of pericardium     internal intercostal muscle N1   pericardial sac N1   transversus thoracis     transverse pericardial sinus N1         visceral layer of pericardium (epicardium)                                                   |Topic and Text Reference | Learning Objectives | Special Instructions | Clinical Exercises | Key Structures
