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.
Each lung is divided into lobes. The right lung has three, but the left lung has only two, thus allowing room to accommodate the heart. Together, the lungsâ tissue surface is almost 40 times greater than the bodyâs outer surface, making the lungs (together) one of the largest organs in the body. Each lung houses a bronchial tree, which gets its name from the intricate network of air passages that supply the lungs with air.
