The vestibulospinal tract is a neural tract in the central nervous system. Specifically, it is a component of the extrapyramidal system and is classified as a component of the medial pathway. Like other descending motor pathways, the vestibulospinal fibers of the tract relay information from nuclei to motor neurons. The vestibular nuclei receive information through the vestibulocochlear nerve about changes in the orientation of the head. The nuclei relay motor commands through the vestibulospinal tract. The function of these motors commands are to alter muscle tone, extend, and change the position of the limbs and head with the goal of supporting posture and maintaining balance of the body and head.

Famous quotes containing the word tract:
“My only companions were the mice, which came to pick up the crumbs that had been left in those scraps of paper; still, as everywhere, pensioners on man, and not unwisely improving this elevated tract for their habitation. They nibbled what was for them; I nibbled what was for me.”
—Henry David Thoreau (1817–1862)
