Tractus vestibulospinalis

tractus vestibulospinalis –>
vestibulospinal tract
A somatopically organised fibre 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 fibres at all levels to the medial part of the anterior horn. Excitatory impulses conveyed by the vestibulospinal tract increase extensor muscle tone.
Synonym: tractus vestibulospinalis, deiterospinal tract.
