A nerve network or plexus located in the cervical (neck) region of the spine, such as the cervical plexus.
From Latin cervix (neck) plus plexus (network/braid); a medical anatomical term describing the interconnected nerves that branch from the cervical spine.
The cervical plexus is like a biological internet router in your neck—all the nerves carrying signals to your shoulders, arms, and diaphragm pass through it, which is why a neck injury can affect so much of your body.
