  2. Spinothalamic tract - Wikipedia

    en.wikipedia.org/wiki/Spinothalamic_tract

    The spinothalamic tract is a nerve tract in the anterolateral system in the spinal cord. [1] This tract is an ascending sensory pathway to the thalamus . From the ventral posterolateral nucleus in the thalamus, sensory information is relayed upward to the somatosensory cortex of the postcentral gyrus .

  3. Spinomesencephalic pathway - Wikipedia

    en.wikipedia.org/wiki/Spinotectal_tract

    The anterolateral system (ALS) is a bundle of afferent somatosensory fibers from different ascending tracts in the spinal cord. These fibers include those of the spinomesencephalic tract, spinothalamic tract, and spinoreticular tract amongst others. [5] Spinomesencephalic fibres project to the periaqueductal gray, and to the tectum.

  5. Dorsal column–medial lemniscus pathway - Wikipedia

    en.wikipedia.org/wiki/Dorsal_column–medial...

    The dorsal column–medial lemniscus pathway (DCML) (also known as the posterior column-medial lemniscus pathway (PCML) is the major sensory pathway of the central nervous system that conveys sensations of fine touch, vibration, two-point discrimination, and proprioception (body position) from the skin and joints.

  6. Posterolateral tract - Wikipedia

    en.wikipedia.org/wiki/Posterolateral_tract

    These axons enter the spinal column and penetrate the grey matter of the dorsal horn, where they synapse on second-order neurons in either the substantia gelatinosa of Rolando or the nucleus proprius. Those neurons project their axon to the anterolateral quadrant of the contralateral half of the spinal cord, where they give the spinothalamic tract.

  7. Spinocerebellar tracts - Wikipedia

    en.wikipedia.org/wiki/Spinocerebellar_tracts

    The spinocerebellar tracts are nerve tracts originating in the spinal cord and terminating in the same side (ipsilateral) of the cerebellum. The two main tracts are the dorsal spinocerebellar tract, and the ventral spinocerebellar tract. Both of these tracts are located in the peripheral region of the lateral funiculi (white matter columns). [1]

  8. Vestibulospinal tract - Wikipedia

    en.wikipedia.org/wiki/Vestibulospinal_tract

    Medial vestibulospinal fibers join with the ipsilateral and contralateral medial longitudinal fasciculus, and descend in the anterior funiculus of the spinal cord. [2] [7] Fibers run down to the anterior funiculus to the cervical spinal cord segments and terminate on neurons of laminae VII and VIII. Unlike the lateral vestibulospinal tract, the ...

  9. Anterior corticospinal tract - Wikipedia

    en.wikipedia.org/wiki/Anterior_corticospinal_tract

    The anterior corticospinal tract (also called the ventral corticospinal tract, medial corticospinal tract, direct pyramidal tract, or anterior cerebrospinal fasciculus) is a small bundle of descending fibers that connect the cerebral cortex to the spinal cord. Descending tracts are pathways by which motor signals are sent from upper motor ...
