DCML - 1) mechanosensory receptors send info to fibers in gracile & cuneate pathways 2) fibers travel to caudal medulla, synapse at dorsal column nucleus (and switch sides) 3) exit DCN as arcuate fibers, cross the midline to form medial lemniscus carries through pons, midbrain, brainstem 4) synapse at thalamus (VPL) 5) internal capsule takes axons to post-central gyrus/S1, some to S2. Meissener - - rapidly adapting -40% of mechanosensory innervation in hand - skin motion, indentation, lo...
