MCQ IN MEDICINE

Detailed explanation-1: -The inner layer is called the visceral pleura and covers the lungs, blood vessels, nerves, and bronchi. There is no anatomical connection between the right and left pleural cavities. [1] With the addition of pleural fluid, the lung pleura allows for easy movement of the lungs and inflation during breathing.

Detailed explanation-2: -The inner pleura, called the visceral pleura, covers the surface of each lung and dips between the lobes of the lung as fissures, and is formed by the invagination of lung buds into each thoracic sac during embryonic development.

Detailed explanation-3: -Pulmonary System Pleurae are serous membranes that separate the lungs and the wall of the thoracic cavity. The visceral pleura covers the surface of the lungs, and the parietal pleura covers the inside of the thorax, mediastinum, and diaphragm. A thin film of serous fluid fills the space between the two pleurae.

Detailed explanation-4: -Parietal pleura is further subdivided into:-costal pleura-diaphragmatic pleura-mediastinal pleura &-pleural cupula. Connecting pleura forms the pulmonary ligament. Visceral pleura is also called pulmonary pleura. Pericardium-the pericardial cavity is found within the mediastinum of the thoracic cavity.
