Chapter 13, Problem 3b
Define each of the following terms in your own words, using 20 or fewer words.
b. Nerve plexus
Verified step by step guidance1
Understand that a nerve plexus is a network of intersecting nerves.
Recognize that it is formed by the merging and branching of spinal nerves.
Note that nerve plexuses are responsible for innervating specific regions of the body.
Examples include the cervical, brachial, lumbar, and sacral plexuses.
Summarize: A nerve plexus is a network of spinal nerves that supplies motor and sensory functions to body regions.

Textbook Question
Maria is a 3-year-old who has been diagnosed with CIPA, or congenital insensitivity to pain with anhidrosis. This disease results from a genetic mutation that causes essentially all general sensory neurons to not function properly. What types of sensations will Maria be unable to detect (be specific)? Predict what problems she might face from her condition.
