equate large muscles with strength‚ that is not necessarily so. Strength is not directly proportional to the size of a muscle.

stomach has three layers of non-striated muscle in its wall and an inner lining of columnar epithelium with goblet cells. The tissue connecting the lining with the muscular coat is areolar tissue. Non striated muscle is a type of muscle tissue‚ which is also called involuntary‚ smooth or plain muscle. It still contains the protein filaments; they do not lie in an ordered pattern and therefore do not produce the banding characteristics of striated muscle. The muscle fibres are spindle or cigar shaped

Exercise works by working the muscles in the affected area‚ this leads to an increased demand on blood in the worked area which results in an increase in blood flow to the area. The increased blood flow leads to the opening of the arteries over time. Applying heat is used

Introduction: Every muscle has lactic acid.According to many people Lactic acid is nasty stuff produced in our muscles during exercise‚ cause soreness‚ muscle fatigue‚ does not contribute to exercise performance‚ muscle does not use it for fuel‚ and better athletes makes less of it. But they all are wrong or in other words they are a lay. Instead Lactate acid is made of Lactate ion called (Lactate) and Hydrogen Ion.
