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.

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.
Bronchi (singular: bronchus) Each bronchus leads to one of the lungs. Bronchi are air passage ways in the lungs. Within each lung, the large bronchi subdivides into smaller bronchi, which lead to even smaller air passageways called bronchioles. These continue to subdivide until they reach a series of dead ends were there are millions of tiny air sacs called alveoli.
