Muscle function: 1. contraction for locomotion and skeletal movement. 2. contraction for propulsion. 3. contraction for pressure regulation. Muscle classification: muscle tissue may be classified according to a morphological classification or a functional classification.ardiac muscle cells are not as long as skeletal muscles cells and often are branched cells. Cardiac muscle cells may be mononucleated or binucleated. In either case the nuclei are located centrally in the cell. Cardiac muscle is also striated.

Yet many people go to the doctor for nonspecific back pain, where they are often given prescription pain relievers and/or are sent for expensive tests. (Of course, if you have severe pain and/or have been injured, you should go to the doctor immediately.) A recent study categorized treatments offered in nearly 24,000 patient visits for back or neck pain over a 12-year period.
