What would the motor units have the fewest muscle fibers Eye muscles calf muscles muscles for posture in back muscle of neck or thigh muscles?

The motor units with the fewest muscle fibers are typically found in the eye muscles. These muscles require precise and fine control for quick and accurate movements, which is why they have a low ratio of muscle fibers to motor neurons. In contrast, muscles like those in the calf or thigh have larger motor units to manage more powerful, less precise movements.
