Chapter 13, Problem 3c
Define each of the following terms in your own words, using 20 or fewer words.
c. Posterior root ganglion
Verified step by step guidance1
Understand that the posterior root ganglion is part of the peripheral nervous system.
Recognize that it contains the cell bodies of sensory neurons responsible for transmitting sensory information.
Note that it is located in the posterior (dorsal) root of a spinal nerve.
Learn that sensory signals from the body travel through the posterior root ganglion to the spinal cord.
Remember that it plays a critical role in processing sensory input like pain, temperature, and touch.
