Anatomy/Pathogenesis. Pincer-type FAI is secondary to acetabular overcoverage, and. although this is typically anteriorly based, overcoverage can. be present superiorly and posteriorly as well.1-14 This acetab-. ular overcoverage results in impingement of the acetabular. rim against the femoral neck during range of motion. The.
They are supported by the surrounding lung tissue. The lungs are slightly different on each side. The right lung is divided into 3 sections called the upper, middle and lower lobes. The left lung is divided into 2 sections called the upper and lower lobes.
Superior vena cava. The lung consists of five lobes. The left lung has a superior and inferior lobe, while the right lung has superior, middle, and inferior lobes. Thin walls of tissue called fissures separate the different lobes. The superior lobes of each lung are the uppermost pieces, also called the upper lobes.Each lobe receives air from its own branch of the bronchial tree, called lobar (or secondary) bronchi. Within the lungs, these bronchi are divided into smaller tubes. The smallest of these tubes is called a bronchiole.he left lung has a superior and inferior lobe, while the right lung has superior, middle, and inferior lobes. Thin walls of tissue called fissures separate the different lobes. The superior lobes of each lung are the uppermost pieces, also called the upper lobes.
