How well do you understand reflexes?

• Green: I get it! I can teach a classmate.

• Yellow: I kind of understand but I need a refresher.

• Red: I don't understand at all. I need you to reteach it.

• an automatic, involuntary action

What does "automatic and involuntary" mean?

• automatic: spontaneous, unconscious (think, kicking when the doctor taps a certain spot on your knee)

• involuntary: you don't decide to do it, it just happens (think, blinking)

Remember!

• You don't think about doing a reflex.

• The reflex just happens, automatically!
