Answer #1

Major somatosensory pathways of CNS include

a)dorsal column pathway

b)anterolateral pathway

These two pathways are sensory in function. Motor function is performed by lateral corticospinal tracts .

The dorsal column medial lemniscus pathway(DCML) is also known as posterior column medial lemniscus pathway (PCML).

This is a sensory pathway of CNS.

It relays sensations of fine touch , vibrations , proprioception (awareness of position).

Pain, temperature ,crude touch are relayed by antero lateral pathways.

So the answer includes proprioception , vibrations and fine touch.

(Crude touch by anterolateral pathway)
