| Anatomical terminology | |
The rubrospinal tract is one of the descending tracts of the spinal cord. It is a motor control pathway that originates in the red nucleus.[1] It is a part of the lateral indirect extrapyramidal tract.
The rubrospinal tract fibers are efferent nerve fibers from the magnocellular part of the red nucleus. (Rubro-olivary fibers are efferents from the parvocelluar part of the red nucleus).[2]
It is functionally less important in humans.[3] It is involved in motor control of distal flexors of the upper limb—especially of the hand and fingers[4]—by promoting flexor tone while inhibiting extensors.[3]
