Add to dictionary

pleurae

[ˈplʊərə ]

Definition

Context #1 | Noun

anatomy, medical

Pleurae are two thin layers of tissue that cover the lungs and line the chest cavity. They are crucial for normal respiratory function. The space between the two pleurae is known as the pleural cavity, which contains pleural fluid to reduce friction during breathing. Any inflammation or disease affecting the pleurae can lead to significant respiratory issues.

Synonyms

lung lining, pleural membranes.

Examples of usage

  • The pleurae allow smooth movement of the lungs.
  • The doctor examined the pleurae for signs of infection.
  • Pleural effusion causes fluid to accumulate between the pleurae.

Interesting Facts

Anatomy

  • Pleurae are comprised of two layers: the visceral pleura, which touches the lungs, and the parietal pleura, which lines the chest wall.
  • These membranes create a pleural cavity that contains a small amount of fluid, reducing friction during breathing.
  • During breathing, the pleurae allow the lungs to expand and contract smoothly, making it easier to inhale and exhale.

Medical Significance

  • Conditions like pleuritis occur when the pleurae become inflamed, leading to sharp chest pain during breathing.
  • Pleural effusion is when excess fluid accumulates in the pleural cavity, often indicating a serious underlying condition.
  • Doctors often use pleural taps to extract fluid from the pleural space for diagnostic purposes.

Cultural References

  • The concept of pleurae is referenced in various medical dramas to highlight urgent respiratory issues faced by characters.
  • Artistic depictions of the human body often simplify pleurae but emphasize their critical role in respiratory health.
  • Educational animations often illustrate the pleurae to help students understand lung mechanics and health.

Physiology

  • The pleurae play a vital role in enabling lung movements and ensuring that the pressure difference allows for efficient respiration.
  • Any disruption in the pleural function can lead to significant respiratory problems, highlighting their importance in daily breathing.
  • Research continues on the pleurae to uncover their roles in various lung diseases and potential treatments.

Origin of 'pleurae'

Main points about word origin

  • The word comes from the Greek word 'pleura,' which means 'side' or 'rib,' indicating its location in the body.
  • In Latin, 'pleura' is also used, maintaining its root meaning related to the sides of the body.
  • Historically, the term began to be used in medical texts around the 16th century to describe the membranes protecting the lungs.

The term 'pleurae' derives from the Ancient Greek word 'pleura', meaning 'side' or 'rib'. It evolved to describe the membranes surrounding the lungs, reflecting their protective role. The usage in medical terminology became prominent with the development of anatomy as a scientific discipline in the Renaissance period. The plural form 'pleurae' emphasizes the existence of both the visceral and parietal layers that make up the pleural structure. This distinction is important in medical contexts, as different conditions can affect one layer or both, illustrating the complexity of respiratory health.
