What happens when you get a concussion?
You asked us, "What happens when you get a concussion?"
Well, our brains may be the consistency of Jell-O.
But luckily - encased in bone, wrapped in membranes and floating in fluid - they're also one of the best-protected organs in our body...until we get whacked on the head or violently tossed around.
Then those delicate brains can end up bumping and twisting around in our skulls.
And one result might be a concussion - a traumatic injury that at least temporarily alters the way our brains work.
That's because nerve cells can get stretched, affecting their ability to send and receive messages to and from the rest of the body.
And those protective membranes surrounding our brains? Well, they can tear, letting toxic substances leak into brain tissue, causing cell death.
Like any other bruised flesh, the brain might also swell during a concussion.
And without a whole lot of room to expand, it can end up pressing against the skull, causing even more damage.
Multiple concussions add up over time, leading to problems with memory loss, depression and even dementia.
So today's lesson? Be careful with your Jell-O brain.
Mmmm ... Brains! Brains!
