Conversation

I just learned about the concept of excitation in my biology class.

Oh really? What does it involve?

It’s about how cells respond to stimulation, which is pretty fascinating.

Root Explanation

Excitation → It is formed from "ex-" (meaning out of or from) and "citare" (meaning to call or summon). The word "excitation" refers to the act of calling forth or stirring up energy or activity.

Memory Tip

Think of 'calling out' ('citare') from 'out of' ('ex-') — that's why excitation means stirring up energy or activity.
