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.
The lungs are the body's major organs of respiration. The two vital parts that make up the lungs are located on each side of the chest within the rib cage. They are separated by the heart and other contents of the mediastinumthe tissues and organs of the middle chest (e.g., the heart and large vessels, windpipe).he essential tissue of the lung lung parenchyma is made up of clusters of spongy air sacs called lobules. There are about 130,000 primary lobules in each lung. Each lobule is approximately 3.5 millimeters in diameter and contains about 2,200 alveoli (air sacs and ducts).
