psych 115 midterm 1 UCLA Exam Questions and Answers 100% Pass 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...
