- preganglionic: proximal to the dorsal ganglion
- postganglionic: distal to the dorsal ganglion
Case Discussion
Approximate MRI anatomy of the brachial plexus, including the preganglionic rootlets.
Radiology Technologists Drink Cold Beer is a helpful mnemonic to remember component of the brachial plexus:
- Roots
- Trunks
- Divisions
- Cords
- Branches
