What are reflexes?? Jackson Ungar

If you've ever been to the doctor for an appointment, you may have experienced a test involving a hammer. Not the kind you might find in your toolbox in the garage. Instead, the doctor's hammer is small and has a rubber tip. The doctor probably used this hammer to tap your knee. When he did that, your leg probably kicked forward before you even realized what was happening. What's going on here? The doctor was simply testing your reflexes. Reflexes are actions your body takes in response to certain events. This means it's automatic. Reflexes occur without your having to think about it. Reflexes are simply natural reactions we're all born with. In fact, they're a sign you're healthy. That's why doctors test for them.

You may be asking, why do you have reflexes? They're actually built in safety mechanism that helps you to keep you safe and healthy. Reflexes protect your body from harmful things. For example, if you ever picked up something that was hot enough to burn your hand before your brain can even register the fact that what you picked up was too hot, your body has already acted to remove your hand from the source of heat.

You're probably familiar with a couple of other reflexes. Even if you didn't realize they were reflexes. Since you've been reading this presentation you've probably blinked several times. Blinking is a reflex that protects your eyes by keeping dust and other particles out while also keeping your eyes moist.
