Central nervous system pathways

Central nervous system pathways" refers to anatomical tracts within the brain and spinal cord that transmit sensory, motor, and integrative signals. These include major ascending (sensory) tracts such as the spinothalamic tract—which relays pain, temperature, and crude touch—and spinocerebellar tracts for proprioceptive information. Descending (motor) tracts include the corticospinal tract for voluntary movement control and corticobulbar tract for cranial nerve motor function. These are not single molecules or receptors but rather collections of axons forming communication routes essential for normal neurological function[4]. **Note:** "Central nervous system pathways" is not a molecular target such as a receptor, enzyme, transporter, or ion channel; it is an anatomical/functional concept describing bundles of nerve fibers in the CNS. Therefore, it does not have canonical molecular identifiers or direct drug interactions typical of therapeutic targets. This entry should be flagged as incorrect if used in contexts requiring specific molecular targets.
