Dermatomes : Mnemonic

Note: C1 doesn’t have a sensory branch

For the purpose of making learning easier, we divide the remaining dermatomal segments into 4 groups which will be accompanied by analogies and mnemonics.

C2-C4

These supply the “hooded cape” region.

C5-T1

Dermatome C7 extends to the middle finger and divides dermatomes C5 and C6 (lateral) from C8 through T1 (medial).

T2-L1

These are present over the trunk and progresses sequentially from top to bottom. Remembering important landmarks is helpful.

S2-S5

2, 3, 4, 5, stand on S1, lie on S2, sit on S3, wipe S4/S5

Also note that: L5 is for Large toe and S1 is for Small toe
