1

dorsal root axons carrying epicritic from UPPER limb go to the 

cuneate fasciulus (more laterally)

2

dorsal root axons carrying epicritic from LOWER limb go to the 

gracile fasciulus 

3

from the gracile and cuneate fascilus goes axons synapse in the

gracile and cuneate nuclei in the MEDULLA

4

from the gracile and cuneate nuclei in the medulla

axons CROSS at the decussations in the MEDULLA

5

after crossing the second order neuron ascend as the ____ to the thalamus

medial lemniscus pathway 

6

the fibers of the medial lemniscus pathway travel up the brainstem from the medulla to synapse at the ____ in the thalamus

VPL

7

from the VPL, the third order nerons synapse in the
