    The corticospinal tract and the rubrospinal tract belong to the lateral system which provides fine control of movement. [42] Spinal cord tracts - reticulospinal tract labeled in red, near-center at left in figure. The reticulospinal tracts are the medial reticulospinal tract, and the lateral reticulospinal tract. [citation needed]

  3. Lateral corticospinal tract - Wikipedia

    en.wikipedia.org/wiki/Lateral_corticospinal_tract

    The lateral corticospinal tract (also called the crossed pyramidal tract or lateral cerebrospinal fasciculus) is the largest part of the corticospinal tract. It extends throughout the entire length of the spinal cord , and on transverse section appears as an oval area in front of the posterior column and medial to the posterior spinocerebellar ...

  4. Extrapyramidal system - Wikipedia

    en.wikipedia.org/wiki/Extrapyramidal_system

    reticulospinal tract: connects the reticular system, a diffuse region of gray matter in the brain stem, to the spinal cord. It also contributes to muscle tone and influences autonomic functions. lateral vestibulospinal tract: Connects the brain stem nuclei of the vestibular system with the spinal cord. This allows posture, movement, and balance ...

  5. Rubrospinal tract - Wikipedia

    en.wikipedia.org/wiki/Rubrospinal_tract

    It is a part of the lateral indirect extrapyramidal tract. The rubrospinal tract fibers are efferent nerve fibers from the magnocellular part of the red nucleus. (Rubro-olivary fibers are efferents from the parvocelluar part of the red nucleus). [2] It is functionally less important in humans. [3]

  7. Lateral vestibulospinal tract - Wikipedia

    en.wikipedia.org/wiki/Lateral_vestibulospinal_tract

    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).

  8. Spinoreticular tract - Wikipedia

    en.wikipedia.org/wiki/Spinoreticular_tract

    These interneurons then synapse with second-order neurons in laminae V-VIII [1] Their axons then ascend in the spinal cord near the lateral spinothalamic tract. [2] A minority of second-order axons of the spinoreticular tract bypass the reticular formation, and project directly to the intralaminar thalamic nuclei.. [1] [page needed]

  9. Abnormal posturing - Wikipedia

    en.wikipedia.org/wiki/Abnormal_posturing

    The second component of decorticate posturing is the disruption of the lateral corticospinal tract which facilitates motor neurons in the lower spinal cord supplying flexor muscles of the lower extremities. Since the corticospinal tract is interrupted, the pontine reticulospinal and the medial and lateral vestibulospinal biased extension tracts ...
