Ascending Pathways
Ascending Neuro Tract Pathways
Question | Answer |
---|---|
Dorsal Column/medial lemniscus Pathway | dorsal horn > ascends up sc IL > cross in medulla > terminate in CL VPL > 3,1,2 |
Anterior Spinocerebellar Pathway | enters dorsal root > immediately crosses > ascends to cerebellum |
Posterior Spinocerebellar Pathway | enters dorsal root below T6 > stays IL > ascends to cerebellum |
Cuneocerebellar Pathway | enters dorsal root above T6 > stays IL > ascends to cerebellum |
Lateral Spinothalamic Pathway | enter spinal cord > terminate in layer 1 IL dorsal horn > cross immediately > ascends CL > VPL (from the body) > 3,1,2 |
Anterior Spinothalamic Pathway | layer 2 and 3 of IL dorsal horn > crosses immediatly > ascends CL ( to different sports) > insula/cingulate gyrus |
Sensory Trigeminal Pathway | enters in pons > crosses immediately > CL VPM or VPI -> cortex 3,1,2 |
Spinal Trigeminal Pathway | enter brainstem at pons> descends IL-> cross in medulla > ascends as part of ventral trigeminal tract to VPM or IL > 3,1,2 or insula/cingulate gyrus |
