A light area in the middle of the A band is called the H (heller) zone, observed only when the myofibril is in a relaxed state. These results thus implicate Cx50 not only in the maintenance of lens transparency but also in the growth of the eye. Proteomic studies have demonstrated an interaction of both filensin and phakinin with AQP0 at the cell membrane. For now it is proposed that the mid-dorsal and mid-ventral epidermal cells impart a special quality to their basal laminae that provides for differential adhesion. The epimysium surrounds bundles of nerve cells that run in long fibers, called fascicles. An activator of MGF is mechanical tension and it has a threshold; thus tension needs to reach a certain intensity to be effective. CallUrl('www>course-notes>orgnet
