2024年10月22日 · Lung fissures are double-folds of visceral pleura that either completely or incompletely invaginate lung parenchyma to form the lung lobes. Each lung has an oblique fissure, also known as the major fissure, that separates the upper lobes from the lower lobes.

2025年2月4日 · Understanding the configuration of lung lobes and fissures is crucial for comprehending how the lungs operate and how various respiratory diseases affect them. This article explains the detailed anatomy of the lung lobes and fissures, highlighting their significance in both health and pathology.

2024年12月27日 · Let’s embark on a journey to decode the intricate world of lung anatomy and explore the fascinating lung segments bounded by fissures. These anatomical landmarks play a crucial role in understanding lung function and diagnosing lung abnormalities.

The right lung has two fissures, oblique fissure and horizontal fissure, which separate the lung into three lobes - upper, middle, and lower. Each lobe has its own visceral pleural covering. Only the horizontal fissure is commonly seen on a frontal chest X-ray.

2024年4月20日 · Oblique and horizontal fissures separate the right lung's 3 lobes. The oblique fissure divides the RML and RLL, while the horizontal fissure divides the RUL and RML. The left lung only has an oblique fissure, separating LUL and LLL.

The normal pulmonary fissures include right oblique fissure, left oblique fissure and right horizontal fissure while the accessory pulmonary fissures include superior accessory fissure, inferior accessory fissure and azygos fissure.

2022年10月10日 · An interactive tutorial that demonstrates the anatomy of lung lobes and fissures, describing the surface anatomy of the lungs.

Each lung is conical in shape and is divided into lobes by double folds of visceral pleura called fissures. Anatomically, the right lung is divided into upper, middle, and lower lobes by oblique and horizontal fissures, and the left lung is divided into upper and lower lobes by an oblique fissure.

2016年3月2日 · Each lung is divided into lobes surrounded by pleura. There are two lobes on the left: the upper and lower, separated by the major (oblique) fissure; and three on the right: the upper, middle and lower lobes, separated by the major (oblique) and minor (horizontal) fissures.

2019年7月20日 · The outer surfaces of both lungs are covered by visceral pleura, which also surrounds the lobes and is reflected into the interlobar fissures, where it forms a double layer. The interlobar fissures are visible on chest radiographs when they are tangential to the X-ray beam.
