Vestibulospinal tract
(Redirected from Tractus vestibulospinalis)
Vestibulospinal tract is a part of the central nervous system that contributes to the control of muscle tone, reflex, and movement. It is one of the descending spinal tracts in the brainstem and plays a crucial role in maintaining balance and posture.
Etymology[edit | edit source]
The term "vestibulospinal" is derived from the Latin words "vestibulum" which means entrance, and "spinalis" which pertains to the spine. This is because the tract originates in the vestibular nuclei located in the brainstem and descends to the spinal cord.
Anatomy[edit | edit source]
The vestibulospinal tract originates in the vestibular nuclei of the brainstem. It is divided into two tracts: the lateral vestibulospinal tract and the medial vestibulospinal tract.
Lateral Vestibulospinal Tract[edit | edit source]
The lateral vestibulospinal tract (LVST) originates in the lateral vestibular nucleus. It descends ipsilaterally in the anterior part of the spinal cord and influences neurons in the spinal cord that control extensor muscles in the trunk and limbs.
Medial Vestibulospinal Tract[edit | edit source]
The medial vestibulospinal tract (MVST) originates in the medial and inferior vestibular nuclei. It descends bilaterally in the medial longitudinal fasciculus of the spinal cord and influences neurons that control neck muscles.
Function[edit | edit source]
The vestibulospinal tract is responsible for maintaining balance and posture. It does this by adjusting muscle tone, extending the limbs, and positioning the head in response to changes in body position. It also plays a role in the vestibulo-ocular reflex, which allows the eyes to remain focused on an object while the head is moving.
Clinical Significance[edit | edit source]
Damage to the vestibulospinal tract can result in a variety of symptoms, including vertigo, nystagmus, and ataxia. These symptoms are often associated with conditions such as Meniere's disease, vestibular neuritis, and labyrinthitis.
