If vomiting episodes are triggered by stress or excitement, try during a symptom-free interval to find ways to reduce stress and stay calm. Eating three small meals and three snacks daily, instead of three large meals, also may help.
Smooth muscle is fundamentally different from skeletal muscle and cardiac muscle in terms of structure, function, regulation of contraction, and excitation-contraction coupling. Smooth muscle cells known as myocytes, have a fusiform shape and, like striated muscle, can tense and relax. However, smooth muscle tissue tends to demonstrate greater elasticity and function within a larger length-tension curve than striated muscle.
Generally, smooth muscle has to be able to contract continuously at a low level of intensity. The structure of smooth muscle enables it to function in this manner and differentiates it from other types of muscle found in the heart and musculature of the arms, legs, back and trunk.he nucleus of a smooth muscle cell, which contains the DNA, is located in the center of the cell, where the cell is widest. In the vicinity of the nucleus are various organelles, which are individual structures with specific cell functions.
