lateral vestibulospinal tract

(redirected from vestibulospinal)

lateral ves·tib·u·lo·spi·nal tract

a somatopically organized fiber bundle originating from the lateral vestibular nucleus (nucleus of Deiters), which descends uncrossed into the anterior funiculus of the spinal cord lateral to the anterior median fissure; the tractus extends throughout the length of the cord, distributing fibers at all levels to the medial part of the anterior horn. Excitatory impulses conveyed by the vestibulospinal tract increase extensor muscle tone.
