Brachial Plexus Mnemonic: Randy Travis Drinks Cold Beer
Use "Randy Travis Drinks Cold Beer" to recall the brachial plexus from roots to branches: Randy = Roots (C5–T1), Travis = Trunks (superior, middle, inferior), Drinks = Divisions (anterior and posterior), Cold = Cords (lateral, posterior, medial), Beer = Branches (musculocutaneous, axillary, radial, median, ulnar).
The mnemonic for the parts
"Randy Travis Drinks Cold Beer" gives the brachial plexus in order from the spine to the arm: Randy for roots, Travis for trunks, Drinks for divisions, Cold for cords, and Beer for branches. Each keyword starts with the same letter as the part it represents.
Say the phrase once, then list the parts beside each word. For the brachial plexus, the roots are C5, C6, C7, C8, and T1; the trunks are superior, middle, and inferior; the divisions are anterior and posterior; the cords are lateral, posterior, and medial; and the branches are the five terminal nerves.
To use the mnemonic, write the first letters R, T, D, C, B vertically and then fill in the full names. This works for both the word list and the anatomical sequence from neck to arm. Practice naming the parts out loud while pointing to your neck and arm.
What each part is
The brachial plexus is the nerve network that supplies the upper limb. Its parts follow the mnemonic from proximal to distal, and each layer feeds the next.
The roots are the C5–T1 ventral rami. They combine into three trunks, each of which splits into an anterior and a posterior division. The divisions then regroup into three cords named by their position relative to the axillary artery: lateral, posterior, and medial.
From the cords arise the five terminal branches—musculocutaneous, axillary, radial, median, and ulnar—which travel into the arm, forearm, and hand. You can use the table below as a quick reference. Memorizing the five terminal branches is often the goal of the mnemonic.
| Mnemonic word | Part | What it is |
|---|---|---|
| Randy | Roots | C5, C6, C7, C8, T1 spinal nerve roots |
| Travis | Trunks | Superior, middle, and inferior trunks |
| Drinks | Divisions | Anterior and posterior divisions |
| Cold | Cords | Lateral, posterior, and medial cords |
| Beer | Branches | Musculocutaneous, axillary, radial, median, and ulnar nerves |
The five terminal branches
The mnemonic "My Aunt Really Misses Uncle" gives the first letters of the five terminal branches of the brachial plexus in order: musculocutaneous, axillary, radial, median, and ulnar. These five nerves are the final outputs of the plexus, each carrying motor and sensory fibers to a specific region of the upper limb. Learning exactly which cord each nerve comes from and what it does turns the mnemonic into usable anatomy.
Most terminal branches arise from a single cord, but the median nerve is the exception: it receives contributions from both the lateral and medial cords. The table below lists each branch, its cord or cords of origin, and its main job in the arm and hand.
| Branch | Cord(s) it comes from | Main job |
|---|---|---|
| Musculocutaneous | Lateral cord | Flexes the elbow via biceps brachii and brachialis; gives sensation to the lateral forearm. |
| Axillary | Posterior cord | Powers the deltoid and teres minor to abduct and rotate the arm; sensation over the lateral shoulder. |
| Radial | Posterior cord | Extends the elbow, wrist, and fingers; sensation to posterior arm and forearm, and dorsum of the hand. |
| Median | Lateral and medial cords | Flexes most forearm muscles and the thenar muscles of the thumb; sensation to palm and first three and a half fingers. |
| Ulnar | Medial cord | Controls most intrinsic hand muscles and some forearm flexors; sensation to the medial hand and fourth and fifth fingers. |
Make it stick
Draw the brachial plexus, but start with the classic “M” shape formed by the lateral and medial cords and their terminal branches. The two vertical legs of the M are the lateral and medial cords; the two inner diagonal lines are the musculocutaneous and ulnar nerves; the outer diagonal lines are the contributions that come together as the median nerve. That one shape contains three of the five terminal branches.
Then add the posterior cord behind the M, and draw the axillary and radial nerves coming off it. Cover your drawing and redraw the whole plexus from memory, saying the mnemonic as you go.
- Draw the M shape first: lateral cord on the left, medial cord on the right; the musculocutaneous nerve goes up and left, the ulnar nerve goes down and right, and the two median roots meet in the middle.
- Label each branch as you draw it, and say “My Aunt Really Misses Uncle” to check the order.
- Add the posterior cord behind the M, splitting into the axillary nerve (going to the shoulder) and the radial nerve (going down the back of the arm).
- Cover the page, redraw the M and the posterior cord branches, then uncover to check accuracy.
- Repeat until you can draw the entire terminal branch pattern in under a minute.
Put it in your notes
In anotemy, draw the brachial plexus as a set of boxes and arrows with the pen or mouse. Start with the five terminal branches: loop each nerve name to turn it into a box, then connect the boxes with arrows to show the cords they come from. The text you type around the drawing automatically makes room, so your mnemonic sentence “My Aunt Really Misses Uncle” can sit right beside the diagram. anotemy runs in a modern browser on a laptop or desktop, and on iPad, where Apple Pencil draws and a finger scrolls, so you can sketch the M shape anywhere. Because anotemy is free while in beta, you can draw the plexus, cover it, and redraw it as many times as you need without worrying about cost.
