Spinocerebellar tract
無意識
uncross
Dorsal (posterior) spinocerebellar tract
(no cross)
1. 感覺神經元[右列] →dorsal root ganglion→ intermediate zone
轉接給另一個神經元
2. intermediate zonenucleus dorsalis of Clarke發出,直接往上傳到同側小腦
Lower limb unconscious proprioception
包括muscle spindlegolgi tendon organ

Ventral (anterior) spinocerebellar tract
(cross-cross)
1. 感覺神經元[右列] →dorsal root ganglion→ intermediate zone
轉接給另一個神經元
2. intermediate zonespinal border cell發出,在spinal cord 交叉到對側,在cerebellum又交叉回來,傳入同側小腦
只有golgi tendon organ

Cuneocerebellar tract
1. 感覺神經元[右列] →dorsal root ganglion→上行到lateral cuneate nucleus
轉接給另一個神經元
2. lateral cuneate nucleus發出,往上到同側小腦
Upper limb unconscious proprioception
包括muscle spindlegolgi tendon organ

rostral spinocerebellar tract
