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.
Dogs have right and left lungs, just like humans. Both sides of the lungs are further divided into sections, or lobes. Inside the lungs, the bronchi divide into smaller and smaller tubes, called 'bronchioles,' much like branches of a tree divide into smaller and smaller branches. At a microscopic level, the bronchioles end in small structures called 'alveoli'.
