What are the fissures of the lungs?
Fissures are double folds of pleura that divide the lung into lobes. There are three lobes in the right lung and two in the left lung. The lobes are further divided into segments and then into lobules, which are hexagonal divisions of the lungs that are the smallest visible subdivision.
What is the function of the fissures in the lungs?
In the right lung, the short horizontal fissure runs horizontally from the oblique fissure up to the anterior border and separates a wedge-shaped middle lobe from the upper lobe [1]. The fissures facilitate a uniform expansion of whole lung for more air intake during respiration.
What is horizontal fissure in lungs?
The horizontal fissure (also called the minor fissure) is a unilateral structure in the right lung that separates the right middle lobe from the right upper lobe.
What are the lobes and fissures in each lung R and L )?
The left lung consists of two lobes: the left upper lobe (LUL) and the left lower lobe (LLL). The right lobe is divided by an oblique and horizontal fissure, where the horizontal fissure divides the upper and middle lobe, and the oblique fissure divides the middle and lower lobes.
What is the major fissure of the lung?
The left lung is divided into two lobes, upper and lower, by the oblique (major) fissure. 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.
What is the major fissure?
The oblique fissures (also called the major fissures or greater fissures) are bilateral structures in both lungs separating the lung lobes.
How many fissures are in the right lung?
The right lung has two fissures, oblique fissure and horizontal fissure, which separate the lung into three lobes – upper, middle, and lower.
Where are the fissures of the lungs?
Each lung has an oblique fissure separating the upper lobes from the lower lobes and the right lung has a horizontal fissure that separates the right upper lobe from the middle lobe. There are numerous accessory fissures that are common anatomical variants.
