Atelectasis is the partial collapse or closure of a lung resulting in reduced or absence in gas exchange. It is usually unilateral, affecting part or all of one lung. [2] It is a condition where the alveoli are deflated down to little or no volume, as distinct from pulmonary consolidation, in which they are filled with liquid.
The lingula is a small tongue-shaped process, consisting of four or five folia; it lies in front of the lobulus centralis, and is concealed by it. Anteriorly, it rests on the dorsal surface of the anterior medullary velum , and its white substance is continuous with that of the velum.
The lingula is the first lobule of the upper portion of the vermis on the superoinferior axis and pertains to the paleocerebellum together with the central lobule, culmen, pyramid and uvula. It is separated from the central lobule by the pre-central fissure. The central lobule is the second lobule of the upper portion of the vermis on the ...
The right lung has three lobes – upper, middle, and lower (or superior, middle, and inferior), and the left lung has two – upper and lower (or superior and inferior), plus a small tongue-shaped portion of the upper lobe known as the lingula. Each lobe is further divided up into segments called bronchopulmonary segments. Each lung has a ...
On the dorsal surface of its lower half the folia and lingula are prolonged. It forms, together with the superior cerebellar peduncle, [ contradictory ] the roof of the upper part of the fourth ventricle; it is narrow above, where it passes beneath the facial colliculi , and broader below, where it is continuous with the white substance of the ...
