The mnemonic
SCALP
What each word stands for
- SSkin
- CConnective tissue (dense, vascular)
- AAponeurosis (galea aponeurotica)
- LLoose areolar tissue (danger layer)
- PPericranium
Why it matters clinically
Infection in the loose areolar layer spreads to the emissary veins and the cranial cavity.
Where it stops being reliable
Gives layers only; it does not give the blood supply or nerve supply of the scalp.
