• Our muscles can produce very fine movements, such as moving the eyes or fingers, or very rough movements, such as lifting heavy weights.
• Our muscles consist of small fibers called myoglobin which contain oxygen, so that our muscles can work without running out of oxygen.
• If we do not use our muscles for a long time, the muscles can shrink and weaken, a condition called atrophy.
• During exercise, our muscles can experience fatigue due to lack of adequate oxygen and nutrition.
• Our muscles can reduce and enlarge with exercise and the right diet.
