Description[edit | edit source]
The Vestibulospinal tract is infact made of two tracts, the lateral and medial. Each tract is responsible for increasing antigravity muscle tone in response to the head being tiled to one side [1] Fibres of the vestibulospinal tracts, the vestibular neuclei, are associated with the cerebellum, which therefore can subsequently result in the cerebellum indirectly influencing control on the spinal control [2]
Anatomy 
[edit | edit source]
Lateral Vestibulospinal Tract[edit | edit source]
Origin[edit | edit source]
- Lateral vestibular nucleus (Deiters' nucleus) [1]
Course / Path[edit | edit source]
- Fibres descend ipsilaterally though the anterior funiculus of the same side of the spinal cord, synapsing on the extensor antigravity motor neurons.[1][3]
Medial Vestibulospinal Tract[edit | edit source]
Origin[edit | edit source]
Course/ Path[edit | edit source]
Function[edit | edit source]
Lateral Vestibulospinal Tract[edit | edit source]
- Excitation on extensor motor neurons controlling muscle tone in antigravity postural muscles[3]
- In gait selective activity is notes in the motor neuron of the quadriceps of the leading leg following heel strike and is maintained through stance phase[1]
