| Name | Function | Pathway | Tract Direction |
| Corticospinal | Precise & skilled voluntary movement | precentral gyrus- pyramidal decussation- internucial neurons- alpha motor neurons | Descending |
| Reticulospinal | influence unskilled voluntary movements | reticular formatioin- crossed & uncrossed to alpha moter neurons | Descending |
| Reticulospinal | reflex activity | functions by facilitationg or inhibiting motor neurons | Descending |
| Tectospinal | Feflex postural movement to visual stimuli | superior colliculus- cross & decend to cervical internuncial pools | Descending |
| Rubrospinal | Facilitates flexors & inhibits extensors | Red Nucleus- cross and descend to internuncial pools | Descending |
| vestibulospinal | Facilitates extensors & inhibits flexors for BALANCE | lateral vestifular nucleus- descend to internuncial pools | Descending |
| Lateral Spinothalmic | pain & temp | periphery- DRG- cross segmentally & ascend to thalamus- to postcentral gyrus | Ascending |
| Anterior Spinothalamic | crude light touch | periphery- DRG- cross segmentally & go to thalamus- postcentral gyrus | Ascending |
| Dorsal Columns | discriminative touch | periphery- DRG- nuclei gracilis/cuneatus- cross at medulla & ascend to thalamus- postcentral gyrus | Ascending |
| Posterior Spinocerebellar | unconscious proprioception | periphery- DRG- nucleus dorsalis- cross segmentally & ascend through superior cerebellar peduncle to cerebellum | Ascending |
| Anterior Spinocerebellar | unconscious proprioception | periphery- DRG- cross segmentally & ascend through superior cerebellar peduncle to cerebellum | Ascending |
| Spinotectal | spino visual reflexes | periphery- DRG- cross segmentally & ascend to superior colliculus | Ascending |
| Spinoreticular | Levels of consciousness | periphery- DRG- ascend to nuclei of reticular formation | Ascending |
| Spino-olivary | Cutaneous & proprioceptive information | periphery- DRG- cross segmentally & ascend to inferior olive- cross back through inferior peduncle to cerebellum | Ascending |
