When the impulse is conducted to the end of the nerve fiber, acetylcholine is secreted there. This acetylcholine acts on the end plate of the muscle fiber and stimulates it, resulting in an action potential in the plasma membrane of the muscle fiber. In addition, one nerve fiber splits into several branches at the end and attaches to many muscle fibers, making them move at the same time. Therefore, they are called motor units or neuromuscular units. How many muscle fibers a nerve fiber controls is called the nerve dominance ratio, which is about 1:10 in the muscles of the tongue or eyeball that make delicate movements, but up to 1:150 in the muscles of the thigh or stomach. 비앤비 여성전용아로마스웨디시 마사지
