Motor primitives allow integration across scales in the motor system and may link movement construction and circuit organization. This review examines support for primitives, and new data relating primitives to concrete circuit elements across species. Both kinematic motor primitives and muscle synergy/kinetic motor primitives are reviewed. Motor primitives allow a modular hierarchy that may be re-used by volitional systems in novel ways. They can provide a developmental bootstrap for ethologically important actions. Collections of primitives both constrain and facilitate motor acts. Novel motor skill likely requires augmentation to transcend the constraints present in initial collections of low level motor primitives. The benefits, and limitations of motor primitives and the recognized knowledge gaps and needs for future research are briefly discussed.
