Anatomical terminology

The rubrospinal tract is a descending tract of the spinal cord connecting to the red nucleus. It is a part of the lateral indirect extrapyramidal tract.

It is rudimentary[1]: 114  and functionally less important in humans.[1]: 244  It is involved in motor control of distal flexors of the upper limb - especially of the hand and fingers[1]: 114  - by promoting flexor tone while inhibiting extensors.[1]: 242  It complements the lateral corticospinal tract.[1]: 298
