What is the role of Dorsal root ganglion cells? 
• DRG = unipolar neurons in peripheral nervous system 
• Job is to relay somatosensory info from skin to spinal cord 
 
 
Describe a touch stimulus. 
• Touch to skin generates a receptor potential by opening mechanoreceptor Na channels 
• Receptor potential passively propagates (flows) to the integration zone 
• Receptor potential is attenuated (becomes smaller) as it propaga...

RAPID-adapting mechanoreceptors - ️️Meissner and Pacinian 
(dynamic phase QUICKLY becomes static phase) 
dorsal root ganglion (DRG) - ️️(part of the PNS) cluster of cell bodies in the dorsal 
root of a spinal nerve (when the action potential reaches the DRG, it splits into 2 - one 
travels toward the cell body and the other continues down the axon) 
dorsal horn - ️️the POSTERIOR column of grey matter in the spinal cord (shape 
differs depending on spinal segment) - contains SENSORY n...
