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 has three, but the left lung has only two, thus allowing room to accommodate the heart. Together, the lungsâ tissue surface is almost 40 times greater than the bodyâs outer surface, making the lungs (together) one of the largest organs in the body. Each lung houses a bronchial tree, which gets its name from the intricate network of air passages that supply the lungs with air.
