Cervical dystonia. Overview. Cervical dystonia, also called spasmodic torticollis, is a painful condition in which your neck muscles contract involuntarily, causing your head to twist or turn to one side. Cervical dystonia can also cause your head to uncontrollably tilt forward or backward.
2) How many lobes do the lungs have? Why do you think that one side has fewer lobes than the other? There are 5 lobes in the lungs: 2 on the left, and 3 on the right. The left lung only has only 2 lobes because there has to be enough room in the chest for the heart, and the heart sits mostly behind the left lung.
Each lung is divided into lobes; the right lung consists of the superior, middle, and inferior lobes, while the left lung consists of only the superior and inferior lobes. Note that both lungs contain an inferior lobe, and it is roughly a similar size to the superior lobe within each lung.
