"In the single fixed pulley (fig. 1) there is no mechanical advantage, the power and weight being equal. It may be considered as a lever of the first kind with equal arms. In the single movable pulley (fig. 2) where the cords are parallel there is a mechanical advantage, there being an equilibrium when the power is considered as a lever of the second kind, in which the distance of the power from the fulcrum is double hat of the weight from the fulcrum." -Marshall

In the Radiata, the starfish manifests one of the simplest forms of nervous systems. it consists of a central mass, with five arms radiating from it. In the center is the mouth, and beneath it the stomach or gastric cavity, which sends branches to each limb. The nervous system consists of five similar ganglions situated in the central portion at the base of the arms. These ganglions are connected and each sends off nerve-filaments to corresponding limbs.
