Anatomy Flashcards
What surrounds the lungs?
The pleural cavities
What is the pleura?
The single layer of flat cells, mesothelium, and associated layer of supporting connective tissues that line the pleural cavity
What is the parietal pleura?
Pleura associated with the walls of a pleural cavity
What is the visceral pleura?
Pleura that reflects from the medial wall and onto the surface of the lung and adheres and covers the lung
What is the suprapleural membrane?
A dome-like layer of fascia that covers the superior surface of the cervical pleura
What is the function of the suprapleural membrane?
It provides apical support for the pleural cavity in the root of the neck
What is the parietal pleura innervated by?
The somatic afferent fibres
What is the visceral pleura innervated by?
Visceral afferent nerves that accompany bronchial vessels
What is a pleural recess?
It is a potential space within the thoracic cavity where, during expiration, the visceral and parietal pleura are relatively distant
What are the pleural recesses?
The costomediastinal and costodiaphragmatic recess
How does air enter and leave the lungs?
Through the bronchi
What is the root of the lung?
It is a short tubular collection of structures that together attach the lung to structures in the mediastinum
What is located in the root and hilum of the lung?
The bronchi, the pulmonary arteries, the pulmonary veins and the lymphatics
What is in the posterior position of the hilum of the lungs?
The Bronchi
What is in the superior position of the hilum of the lungs?
The Pulmonary arteries
