Conversation

I read this interesting article about how receptors in our cells work.

Oh really? What did it say about them?

It explained that they bind with hormones and neurotransmitters to send signals.

That’s fascinating! I never knew they played such a big role in our bodies.

Root Explanation

Receptor → It is formed from "re-" (meaning again) and "capere" (meaning to seize or take). The word "receptor" refers to something that takes in or receives signals or stimuli again.

Memory Tip

Think of something that 'takes in' ('capere') signals 'again' ('re-') — that's why a receptor is something that receives information.
