What is the Innervation of visceral and parietal pleura?
The visceral pleura is innervated by autonomic nerves that travel with the bronchial blood vessels. The parietal pleura is innervated by somatic nerves, specifically the intercostal nerves and the phrenic nerve.
The 2 pleural membranes?
The two pleural membranes are the visceral pleura and the parietal pleura. The visceral pleura is the innermost layer that covers the surface of the lungs, while the parietal pleura lines the chest cavity. These membranes create a fluid-filled space called the pleural cavity, which helps to reduce friction and allows for smooth movement of the lungs during breathing.
Where is lubricating fluid secreted by the pleura located?
The lubricating fluid secreted by the pleura is located between the two layers of the pleural membrane: the visceral and parietal pleura. This fluid helps reduce friction between the two layers during breathing movements.
What does the plural fluid do?
The plural fluid about 1 to 2 ml lubricates the visceral and parietal pleura during inspiration and expiration.
Where is the visceral pleura?
The visceral pleura, adheres closely to the subjacent alveoli of the lung.
