Relating to the outer layer of skin or bark.
The epidermic layer protects the body from external elements.
Epidermic → It is formed from "epi-" (meaning upon or over) and "derma" (from Greek, meaning skin). The word "epidermic" refers to something that is related to or situated upon the outer layer of skin.
Think of something that is 'upon' ('epi-') the 'skin' ('derma') — that's why epidermic relates to the outer layer of skin.
