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
