Spinal pathways are neural tracts within the spinal cord that act as information highways, connecting the brain to the body, divided into ascending (sensory) pathways carrying signals up (pain, touch, temp) and descending (motor) pathways carrying commands down (movement). Key sensory pathways include the Dorsal Column-Medial Lemniscus (fine touch) and Spinothalamic (pain/temp), while major motor tracts are the Corticospinal (voluntary movement) and extrapyramidal tracts like Rubrospinal, Vestibulospinal, Reticulospinal. These pathways use chains of neurons, often crossing over (decussating) to relay information between body sides.
