considering that ad-type fibers terminate on adrenaline-storing cells and na type fibers terminate on noradrenaline-storing cells , it is suggested that beta-receptor -- ad-type fibers -- adrenaline-storing cell system controls adrenaline level and alpha-receptor -- na type fibers -- noradrenaline-storing cell system controls noradrenaline level .
