Brachial plexus mnemonic

This was probably the most important answer you must have encountered during your 1st year.

Here are tricks to remember Brachial Plexus!

First of all remember this:
Mnemonic: "Re-Take Drinks & See Birds."
R = Roots (Re)
T = Trunks (Take)
D = Divisions (Drinks)
C = Cords (See)
B = Branches (Birds)

A) Branches of the Roots.
Mnemonic: "She looks pretty sexy & rude."
1) She = Serratus anterior nerve(C5-C7)
2) Looks = Longus colli(C5-C8)
3) Pretty = Phrenic(C4)
4) Sexy = Scaleni muscles (C5-C8)
5) Rude = Rhomboids (C5)

B) Branches of the Trunks
1) Sub-clavius (C5-C6)
2) Suprascapular (C5-C6)
(Remember Sup / b because p is inverted b)

C) Branches of cords 

1) Branches of lateral cord

Mnemonic: "Look miss look."
a) Look = Lateral pectoral (C5-C7)
b) Miss = Musculocutaneous (C5-C7)
c) Look = Lateral root of median (C5-C7)

2) Branches of medial cord 
Mnemonic: "M4U"
a) Medial Pectoral (C8-T1)
b) Medial cutaneous nerve of arm (C8-T1)
c) Medial cutaneous nerve of forearm (C8-T1)
d) Median root of median (C8-T1)
e) Ulnar (C7-T1)

3) Branches of posterior cord
Mnemonic: "ULNAR"
a) U = Upper Subscapular (C5-C6)
b) L = Lower Subscapular (C5-C6)
c) N = Nerve to latissimus dorsi (C6-C8)
d) A = Axillary (C5-C6)
e) R = Radial (C5-T1)
Note: ULNAR is mnemonic for branches of posterior cord, there is no involvement of ulnar nerve here!

  1. U can use ultra instead of ulnar to avoid confusion for posterior cord branches... T for thoracodorsal
