How far is the pleura
author: doctor Salomykova EV
Pleura is located in the chest cavity. To get to the chest cavity, the surgeon needs to go through several layers of tissue. In the beginning it is the skin (contains sebaceous and sweat glands) and subcutaneous fatty tissue. Then comes a layer of muscle tissue. There also passes a large number of blood vessels (arteries and veins) and nerve endings. Thanks to them, nutrition and innervation (delivery of nerve impulses) of the muscles takes place. The finest branches of blood vessels and nerves reach the skin, delivering the necessary substances and providing sensitivity.
In the topographic anatomy, which studies the detailed structure of the human body, several layers of pectoral muscles are divided. Each muscle is a special shell-case with the help of fascia. After the muscular framework, there are bone formations, namely 12 pairs of ribs, thoracic spine and a separate bone - sternum, connected to the upper seven pairs of ribs.
After opening the chest, the surgeon enters the chest cavity. The thoracic cavity is a space bounded by the musculoskeletal framework (ribs) on the sides, in front of the sternum, behind the thoracic spine and from below by the special pectoral muscle - the diaphragm. There are such important organs as the heart and lungs.
The pleura itself is a serous leaf that covers the lungs (visceral pleura) on one side, and the thoracic cavity (parietal pleura) on the other. Thus, a pleural cavity forms between the two layers of the pleura. With various pulmonary diseases, an excessive amount of fluid (effusion) is formed in this space. To understand at what depth the pleura lies - it is necessary to understand what it borders on.
The uppermost part of the pleura was called the dome of the pleura. The dome of the pleura is located a couple of centimeters above the clavicle in front, and behind it is approximately at the level of the spinous processes of the 7 vertebrae of the cervical region. If we talk about other boundaries of the pleura, the posterior and right anterior border of the pleura coincides with the analogous limits of the lungs. The remaining borders of the pleura differ slightly from pulmonary. This is taken into account when examining the patient, as well as during pleural puncture (a pleural cavity puncture with a diagnostic or therapeutic purpose).
The pleura lies deep enough, however, with severe injuries of the thoracic cavity, especially penetrating, the integrity of the pleura often occurs, and in severe cases of the lungs themselves.
Also read an article on the technique of pleural puncture and watch the video.
Alexis Heal: Bless you for making these videos! It's been over a year since I have had anatomy and this is a great refresher (even better than my anatomy professor)! Wish I had you
Thu Truong Minh: so creative, This is the first time I have learnt about pleura in such a creative and attractive way like yours . Thanks for making and uploading this for us :)
bjarasina12: is pleura parietalis attached the to the thoracic cage the same way its attached to the lungs or how?
Rodrigo Diaz R.: U are... FAN TAS TIC!! Can´t tell you thanks enough. So easy is to follow you. Greatings from Chile (Southamerica)
Ryan Evans: Incredibly charismatic and enjoyable to listen to. Please don't ever edit out the goofs. Those make the videos much better! I will be using this video in my own HS anatomy class as well as making my own bottle pleura model. Thank you so much, Sam!
Shahad Alsenidi: Thank you very much! That was very helpful and I'm grateful to you. Channel is shared in my uni! Will make sure everyone I know subscribes to your channel.
Jess Sal: Thanks for the vid! You made it more understanding and entertaining! got the Bill Nye thing goin on(a more laid back one)

The pleural cavity is the space between the inner and outer pleura. The inner sheet of the pleura covers the lungs, and the outer one from the inside lining the thorax. Normally, in the pleural cavity, there is a small amount of fluid necessary for lubrication during the movement of the lungs during breathing.

Pleurosclerosis is a multiple metastasis of a tumor in the pleura that occurs when malignant neoplasms are present in the body.

Pleura is a shell lining the surface of the lungs on one side, and on the other hand lining the thorax from the inside. As a result, between the leaves of the pleura, not a large cavity is formed, containing normally not a large amount of pleural fluid that lubricates the surface of the pleura during movements of the lungs.
Pleuritis is called inflammation of the pleura. On its surface, deposits of fibrin are formed, and inflammatory fluid (exudate) accumulates in its cavity.

Under such a concept as a pleura, a thin serous membrane is meant that covers each lung - it is commonly called the visceral pleura) and lining the walls of the pleural cavity of the lungs (parietal pleura). Pleura has the finest connective tissue base, which is covered with a flat epithelium (mesothelium) and is located on the basal membrane.
