The rubrospinal tract is a part of the nervous system. It is a part of the indirect extra-pyramidal tract and is responsible for large muscle movement such as the arms and the legs.

It facilitates the flexion and inhibits the extension.

This is an alternative route for the mediation of voluntary movement.

It originates in the red nucleus --> crosses to the other side of the midbrain --> descends in the lateral part of the brainstem tegmentum --> travels through the lateral funiculus of the spinal cord in the company with the lateral corticospinal tract.

It is small and rudimentary in humans.
