What are the 5 major nerve plexuses?
- Cervical plexus.
- Brachial plexus.
- Lumbar plexus.
- Sacral plexus.

Where are the plexuses located?
Nerve Junction Boxes: The Plexuses Four nerve plexuses are located in the trunk of the body: The cervical plexus provides nerve connections to the head, neck, and shoulder. The brachial plexus provides connections to the chest, shoulders, upper arms, forearms, and hands.
What does sacral plexus control?
