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.
1 The human left lung is divided into two lobes, an upper and a lower, by the oblique fissure. It has a cardiac notch, a concave impression molded to accommodate the shape of the heart.  The lingula is not technically a lobe, but is the left lung equivalent of the right lungâs middle lobe.
