Ascending tracts
Dorsal column pathways
精細觸覺(2-point discrimination)、震盪、壓、有意識本體覺（proprioception)
Fasciculus cuneatus (upper trunk T6以上靠外側）
1‘DRG>Post. Column
2’同側faciculus cuneatus
2’軸突：internal arcade fibers在 medulla的sensory decision 跨到對側contralateral繼續上行改叫：medial lemniscus
3’Thalamus中的ventral posterolateral nucleus (VPL)
終點：post central gurus in cerebral cortex
Fasciculus gracilis（lower trunk T7以下靠內側)
1’DRG>Post. Column
2’同側Fasciculus gracilis
2’軸突internal arcuate fibers>對側Contralateral >medial lemnisus
3’talamus中的VPL
終點：postcentral gyrus in cerebral cortex
Spinothalamic/anterolateral pathways
Lateral spinothalamic
Pain、temperature
1’DRG
2‘dorsal horn的lamina 1、2、4、5
跨到對側Lateral spinothalamic tract
3’thalamus的ventral posterolateral nucleus
終點：(cerebral cortex)postcentral gyrus
Anterior/ventral spinothalamic
1’DRG
2’灰質區（dorsal horn)的lamina1、2、、4、5
跨到對側anterior spinothalamic tract
3’thalamus的ventral posteriolateral nucleus
終點：(cerebral cortex)postcentral gyrus

Dorsal is nucleus C8-L3/4才有
Cuneocerebellar (posterior external arcuate fiber)
C8以上同側無意識本體
輔助spinocerebellar tract不足
1‘DRG
2’medulla 中的accessory cuneatus nucleus
脊髓上升路徑：同側Fasciculus cuneatus
終點：經下小腦角inferior cerebellar peduncle到達小腦
