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.
The Right and Left Lung. Human lungs are divided into right and left lungs, and further subdivided into lobes. The right and left lung are not symmetrical, since your right lung has three lobes and your left lung has two. The lobes on both sides of your lungs are separated by fissures. The oblique fissure separates the largest lobe, the left upper lobe, or superior lobe, from the one below it.
