Separating straight legs carry the risk of muscle pull of thigh muscles. This is because vibrations stimulate muscle spindles in the calf muscles. Kegel exercises aim to strengthen the pelvic floor muscles. Chest, neck, back, abdominal muscles, and buttocks may be affected. The stimulus voltage stimulates nearby nerves, resulting in contraction of the pelvic muscles and ejaculation. Stretching the leg muscles can bring temporary relief. Glycogen can be found in the skeletal muscles or liver. Their bodies are elongated with weak, watery muscles and skeletal structures. This may then be followed by weakness of the arms, chest muscles, and legs. They have elongated bodies with weak, watery muscles and skeletal structures. Beneficial exercise will be any that strengthens the interosseous muscles and lumbricals. Connective tissue is present in all muscles as fascia. During exhalation the diaphragm and intercostal muscles relax. Neuromuscular diseases are those that affect the muscles and/or their nervous control. Tonic seizures produce constant contractions of the muscles.
