Anatomy of the Lungs and Pleura Quiz

The pleura surrounds the lungs and acts as a protective membrane.

The pleura consists of the parietal layer and the visceral layer.

The diaphragmatic parietal pleura is continuous with the costal parietal pleura at the costodiaphragmatic reflection.

<p>The pleural cavity is a potential space between the visceral and parietal pleura. It contains a layer of serous fluid that reduces friction and provides cohesion between the lung and thoracic wall.</p> Signup and view all the answers

<p>The two types of pleura are the visceral pleura, which covers the lungs, and the parietal pleura, which lines the inner surfaces of the walls of the pleural cavity.</p> Signup and view all the answers

<p>The trachea bifurcates at the level of the sternal angle. The primary bronchi are the two branches that result from the tracheal bifurcation, with the right primary bronchus being wider, shorter, and more vertical, and the left primary bronchus passing inferior to the arch of the aorta and anterior to the esophagus and thoracic aorta.</p> Signup and view all the answers

<p>The costal parietal pleura is continuous anteriorly with the mediastinal parietal pleura at the costomediastinal reflection, posteriorly with the mediastinal parietal pleura at the vertebral bodies, inferiorly with the diaphragmatic parietal pleura at the costodiaphragmatic reflection, and superiorly with the cervical parietal pleura at the level of the 1st rib.</p> Signup and view all the answers

<p>The cupula is the top of the lung and is a serous membrane lining the pleural cavity. It extends above the level of the 1st rib into the root of the neck. It is also known as the cervical parietal pleura or cervical dome of pleura.</p> Signup and view all the answers
