Lecture 3 lungs & pleura
The pleura is a monolayer of mesothelial cells covering the lung and inner surface of the chest cavity, creating the pleural space. The mesothelial cells rest on a matrix of collagen, elastic fibers, blood vessels, and lymphatics, which allow the lung and chest to expand and contract, protected from friction by the pleural fluid and properties of the mesothelial cells. With a rich blood supply.

The pleural reflections may be seen to extend over the surface of the diaphragm. FIG. 26.7. The inferior pulmonary ligaments and pleural reflections over the phrenic nerves. A: HRCT on the right shows the inferior pulmonary ligament as a thin triangular opacity ( large arrow) arising in the region of the esophagus.
5 The Pleura Radiology Key
The lines of pleural reflection are formed by the parietal pleura as it changes direction (reflects) from one wall of the pleural cavity to another. The sternal lines of reflection are where the costal parietal pleura becomes continuous with the mediastinal pleura.

Function Related Conditions Frequently Asked Questions The pleura is a vital part of the respiratory tract. Its role is to cushion the lung and reduce any friction that may develop between the lung, rib cage, and chest cavity. Each pleura (there are two) consists of a two-layered membrane that covers each lung.
Visceral Pleura Definition Anatomy
Knowledge of the anatomy of the lines of pleural reflection, triangular ligaments, and pleural recesses is important to thoracic surgeons because their anatomic areas are used daily for radiographic interpretation as well as for the performance of procedures such as chest tube insertion, thoracentesis, and pericardiocentesis. Their knowledge is.
5 The Pleura Radiology Key
Pleura: Anatomy. The pleura is a serous membrane that lines the walls of the thoracic cavity and the surface of the lungs. This structure of mesodermal origin covers both lungs, the mediastinum, the thoracic surface of the diaphragm, and the inner part of the thoracic cage. The pleura is divided into a visceral pleura and parietal pleura.

Reflections of the Pleura (pleural recesses, ligament and fascia):Commencing at the sternum, the pleura passes lateralward, lines the inner surfaces of the costal cartilages, ribs, and Intercostales, and at the back part of the thorax passes over the sympathetic trunk and its branches, and is reflected upon the sides of the bodies of the vertebr.
Anatomy of the pleura Osmosis
At the inferior aspect of the root, the reflection of the mediastinal pleura over the visceral pleura continues as a bilayered sheet of both visceral and parietal pleura (total of four layers) in the front and back of the hilar plane to form the inferior pulmonary ligament (also known as the triangular ligament), that is carried downward and mor.
hanson's anatomy — Pleural reflections
A pleura is a serous membrane that folds back on itself to form a two-layered membranous pleural sac. The outer layer is called the parietal pleura and attaches to the chest wall. The inner layer is called the visceral pleura and covers the lungs, blood vessels, nerves, and bronchi.
Anatomy of the Pleura Reflection Lines and Recesses Thoracic Surgery Clinics
The pleura is a double-layered serous membrane that covers each lung and lines the thoracic cage. The outer layer ( parietal pleura) attaches to the chest wall. The inner layer (visceral pleura) covers the lungs, neurovascular structures of the mediastinum and the bronchi.
Anatomy of the pleura Osmosis
The lines of pleural reflection outline where parietal pleura abruptly changes direction as it passes from one wall of the pleural cavity to another. Right and left parietal pleura reflect in an asymmetric manner due to the presence of the heart.

Pleural Cavity The pleural cavity is a potential space between the parietal and visceral pleura. It contains a small volume of serous fluid, which has two major functions. It lubricates the surfaces of the pleurae, allowing them to slide over each other.
Anatomy of the pleura Osmosis
Pleural space The pleural cavity surrounds the lungs in the thoracic cavity. There are two pleural cavities, one for each lung on the right and left sides of the mediastinum. Each pleural cavity and it's enclosed lung are lined by a serous membrane called pleura. The right and left pleural cavities are completely independent compartments.

They reflect upon themselves to form two layers of thin, serous membranes that glisten and appear grayish-yellow in color. A potential space called the pleural cavity forms between these layers. In a healthy individual, there is a small amount of fluid within this space.

The visceral and the mediastinal parietal pleurae are connected at the root of the lung ("hilum") through a smooth fold known as pleural reflections, and a bell sleeve -like extension of visceral pleura hanging under to the hilum is known as the pulmonary ligament .
