✅ Overview
The Brachial Plexus is a network of nerves in the shoulder that carries movement and sensory signals from the spinal cord to the arms and hands.
✅ Draw & Understand
MNEMONICS
➡️ Read That Damn Cadaver Book
➡️ Roots, Trunks, Divisions, Cords, Branches
We’ll pair up the root values with our hand and give each finger a root value👇🏽
🖐🏾Thumb C5, Index C6, Middle C7, Ring C8, Pinky T1
Draw 🎨 (as seen in above diagram):
3 letter Y’s, 2 letter E’s and 1 letter X
MNEMONIC
For Main nerves and the root values:
➡️ 3 Musketeers Assassinated 5 Rats, 5 Mice, and 2 Unicorns
*3 Musketeers - we have 3 fingers Thumb C5, Index C6, Middle C7 and the M for musketeers corresponds to M for Musculocutaneous nerve - roots C5, C6, C7
*Assassinated - remember to assassinated someone you have to make a gun sign 👉🏼 with your Thumb C5 and Index C6, and A for Assassinated is A for Axillary nerve - roots C5, C6
*5 Rats and 5 Mice - 5 means all our fingers (all 5 nerve roots) and the R in rats stands for Radial nerve and M for mice stands for Median nerve
*2 Unicorns - 2 is for the last two fingers left, Ring C8 and Pinky T1 and the U in unicorn corresponds to the U in Ulnar nerve C8, T1
✅ 11 Additional Nerves & Root Values
From Roots:
Dorsal Scapular nerve - C5
Subclavius nerve - C5, C6
Suprascapular nerve - C5, C6
Long Thoracic nerve - C5, C6, C7
Lateral Cord:
Lateral Pectoral nerve - C5, C6, C7
Posterior Cord:
Upper subscapular nerve - C5, C6
Lower subscapular nerve - C5, C6
Thoracodorsal nerve - C6, C7, C8
Medial Cord:
Medial pectoral nerve - C8, T1
Medial brachial nerve - C8, T1
Medial antebrachial nerve - C8, T1
We'll discuss brachial plexus injury and more clinical topics soon in the next lesson!
