Mnemonic for Brachial Plexus Nerves: Visual & Interactive List

After decades of teaching anatomy, I can tell you that the brachial plexus is a perennial challenge. Even in 2025, mastering its complex network of roots, trunks, divisions, cords, and branches is fundamental for exams and clinical practice. I’ve seen countless students’ eyes glaze over when this topic comes up. These effective visual and interactive mnemonics, drawn from established medical textbooks and anatomy labs, will help make these nerve pathways stick permanently in your brain. They combine visual anchoring, storytelling, and interactive practice to create multiple pathways for recall.

1. Map the Brachial Plexus Roots on Your Hand

Your hand is the perfect built-in tool for remembering the five spinal nerve roots that form the brachial plexus. For more details on why this works so well, check out the Anesthesia & Analgesia Hand Mnemonic Article:

  • Thumb = C5
  • Index finger = C6
  • Middle finger = C7
  • Ring finger = C8
  • Pinky finger = T1

This simple technique uses your own body as a memory device. Next time you need to recall the roots, just look at your hand. For another concise root-subdivision mnemonic, see the Radiopaedia article on brachial plexus root subdivisions Radiopaedia Root Subdivisions Mnemonic.

2. Master the Main Segments with One Simple Phrase

Remember the major components of the brachial plexus in order with this sports-themed mnemonic:

“Rugby Teams Don’t Cover Bruises” (Rugby Teams Don’t Cover Bruises mnemonic video)

Each word represents a key anatomical segment:

  • Roots (C5–T1)
  • Trunks (upper, middle, lower)
  • Divisions (anterior and posterior)
  • Cords (lateral, medial, posterior)
  • Branches (terminal nerves)

I’ve heard them all, but this sports-themed one seems to stick. Another classic is “Remember To Drink Cold Beer,” which works just as well, though I can’t officially endorse your study methods.

Detailed Formation of Trunks, Divisions, and Cords:

StructureComponentsFormation
Upper TrunkC5–C6Union of C5 and C6 roots
Middle TrunkC7Continuation of C7 root
Lower TrunkC8–T1Union of C8 and T1 roots
Anterior DivisionsAll trunksEach trunk divides into anterior and posterior divisions
Posterior DivisionsAll trunksEach trunk divides into anterior and posterior divisions
Lateral CordC5–C7Anterior divisions of upper and middle trunks
Medial CordC8–T1Anterior division of lower trunk
Posterior CordC5–T1All three posterior divisions

3. Recall Terminal Nerves with a Drinking Reference

Now for the five major terminal branches. This next mnemonic is a bit crude, but you won’t forget it during an exam, and that’s what counts:

“Most Alcoholics Must Really Urinate”

It also handily preserves their lateral-to-medial order:

NerveOrder (Lateral → Medial)Motor FunctionsSensory FunctionsSpinal Roots
MusculocutaneousMost lateralBiceps brachii, brachialis, coracobrachialisLateral forearmC5–C7
AxillaryDeltoid, teres minorLateral shoulder (“regimental badge” area)C5–C6
MedianMost forearm flexors, thenar muscles, lumbricalsLateral palm, palmar aspect of lateral 3½ fingersC5–T1
RadialTriceps, anconeus, forearm extensorsPosterior arm/forearm, dorsum of lateral 3½ fingersC5–T1
UlnarMost medialFlexor carpi ulnaris, medial FDP, intrinsic hand musclesMedial palm, medial 1½ fingersC8–T1

Alternatively, check out Radiopaedia’s mnemonic for terminal branches Radiopaedia Terminal Branches Mnemonic to reinforce this order.

4. Lock In Cord Branches with Targeted Mini-Mnemonics

Now that you have the main highway mapped out, let’s look at the smaller roads. Each cord has its own set of branches that can be remembered with these focused phrases:

Lateral Cord

“Lucy Loves Me” 
  • Lateral pectoral nerve
  • Lateral root of median nerve
  • Musculocutaneous nerve

Medial Cord

“Most Medical Men Use Morphine” 
  • Medial pectoral nerve
  • Medial cutaneous nerve of arm
  • Medial cutaneous nerve of forearm
  • Ulnar nerve
  • Medial root of median nerve

Posterior Cord

“ULTRA” 
  • Upper subscapular nerve
  • Lower subscapular nerve
  • Thoracodorsal nerve
  • Radial nerve
  • Axillary nerve

For more in-depth cord branch mnemonics, check out the Mnemonics.co Brachial Plexus section.

5. Create Interactive Flashcards for Brachial Plexus Practice

Convert these mnemonics into a digital review system:

  • Download a blank brachial plexus diagram
  • Use Anki or Quizlet to create cards with the diagram on one side
  • On the reverse, add labels and corresponding mnemonics
  • Include color-coding for different segments
  • Set up spaced repetition for optimal learning

6. Develop Color-Coded Brachial Plexus Diagrams

Assign specific colors to each major component:

  • Roots: Blue
  • Trunks: Green
  • Divisions: Yellow
  • Cords: Orange
  • Branches: Red

Draw or print a large brachial plexus diagram and highlight each segment with its corresponding color. The visual differentiation helps your brain categorize and recall the structures more easily.

7. Animate the Plexus Path with a Mini-Story

Create a simple story that follows the path of a nerve impulse:

“Five friends (C5–T1) met at three bus stops (trunks). Each bus split into two routes (divisions) but later merged into three main highways (cords). From there, they took five different exits (terminal branches) to reach their destinations.”

Recording yourself explaining this story while drawing the plexus can create a powerful multi-sensory learning experience. For an animated explanation of this mnemonic, visit the Magnetic Memory Method Brachial Plexus Mnemonic.

8. Reinforce Memory with Spaced Repetition Quizzing

Set up a 5-minute daily quiz routine using spaced repetition apps:

  • Monday: Identify roots and trunks
  • Tuesday: Match divisions to trunks
  • Wednesday: Name cord branches
  • Thursday: Trace paths from roots to terminals
  • Friday: Full plexus review

To see how spaced repetition works in practice, check out this Spaced Repetition Quiz Video. Spaced repetition is far more effective than cramming.

10. Apply Mnemonics in Practical Lab Settings

Take your mnemonics into anatomy lab:

  • Label a cadaver or model with sticky notes using the first letters of your mnemonics
  • Trace nerve pathways with your finger while reciting the relevant mnemonic
  • Challenge lab partners to identify structures using your memory devices

For a clinical application: A patient presents with weakness in thumb opposition. Use your mnemonics to trace backwards from the affected muscle through the median nerve, to the lateral and medial cords, anterior divisions, and ultimately to C8–T1 roots.

Expert Sources on Brachial Plexus Memory Techniques

Anatomy instructors consistently highlight the effectiveness of multi-modal learning. Students who combine visual, verbal, and kinesthetic memory techniques tend to score higher on anatomy exams. For additional reference, the guides at TeachMeAnatomy brachial plexus page and the Kenhub Brachial Plexus article are excellent resources.

Furthermore, research published in Anesthesia & Analgesia confirms that the hand mnemonic provides both conceptual understanding and recall for nerve block procedures.

Practice Makes Permanent

These mnemonics work best when applied regularly across different contexts. Start with the basic structure (“Rugby Teams Don’t Cover Bruises”) and the terminal branch sequence (“Most Alcoholics Must Really Urinate”), then gradually incorporate the more specific cord branch mnemonics.
