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.
1 A neurologist (if nerve problems are causing your pain) 2  A psychologist (if your pain is caused or worsened by stress or other psychological issues) 3  An orthopedic surgeon.  A rheumatologist (if your back pain is caused by arthritis or other joint problem)
There's nothing like a doctor for the back. Can be an orthopaedic/neurologist/neurosurgeon. If there's a compression fracture or something like that then an orthopaedic. A case of chronic back pain may be best treated by a neurologist. Something like a nerve pinch may need to be looked at by a neurosurgeon. A lot of these specialities may overlap though.
