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.

Here's a short list: Your family doctor is usually the first place to go at the onset of neck or back pain. If you have a serious problem, she will probably order diagnostic tests, refer you to a specialist and/or help with short-term pain management by prescribing medication. Studies show that family doctors do not easily adapt their practices to new back pain treatments.
