Function: Lateral vestibulospinal tract is excitatory to the spinal motor neurons which supply extensor muscles of neck, back and limbs. It is inhibitory to neurons which supply flexor muscles of limbs. Medial vestibulospinal tract inhibit spinal motor neurons which supply muscles of neck and upper part of back. Reticulospinal Tract.

The medial vestibulospinal tract projects bilaterally within the Jul 7, 2019 Another descending pathway, the medial vestibulospinal tract (MVST) provides reflexive control of the head and neck muscles. This is an integral the vestibulospinal tract) before synapsing on interneurons on the same side of the spinal cord. Other smaller tracts included in the ventromedial pathway are Lateral corticospinal tract; Anterior corticospinal tract. Corticobulbar.
The medial vestibulospinal tract is one of the descending spinal tracts of the ventromedial pathway. The medial part of the vestibulospinal tract is the smaller part

Vestibulospinal Tracts The vestibulospinal system comprises medial and lateral vestibulospinal tracts (Figs. 24.1 and 24.6). The medial vestibulospinal tract is made up of axons that originate in the medial and inferior vestibular nuclei and descend bilaterally into the spinal cord as part of the medial longitudinal fasciculus.
The lateral vestibulospinal tract is one of the descending spinal tracts of the ventromedial funiculus.. The lateral part of the vestibulospinal tract is the major portion and is composed of fibers originating in the lateral, superior, and inferior vestibular nuclei (primarily the lateral). It projects ipsilaterally down to the lumbar region of the spinal cord. The medial vestibulospinal tract, however, arises from the medial vestibular nucleus and descends within the medial longitudinal fasciculus of the brainstem.
