You asked us, "What happens when you get a concussion?"
 
Our brains are the consistency of Jell-O. Luckily they're encased in bone, wrapped in membranes and are 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. It's 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. That allows toxic substances to 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. That can cause 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!

    It was very interesting that your brain swells up when you get a concussion.

    Bruised flesh swells because it is flimsy and very weak so nothing can support it.

    I thought this article was interesting because I did not know that when you get a concussion your head swells up and is bruised on the inside.

    I have had a concussion before, and this article really helped explain it more. I had no idea that the brain actually swelled when it receives trauma!

    Bruised flesh swells because when the brain gets bashed around a lot the nerves stretch and affects the nerves reaction and the brain hits your skull and causes even more damage.
    I think this article is really interesting because I didn't know how concussions were formed and a lot of other people don't know either so it could be helpful to some people.

    Bruised flesh swells because it is not strong and there is nothing to protect it. I found this interesting because i have seen somebody getting a concussion and i was wondering why it hurts so much and how it was different then just hitting your head.

    Bruised flesh swells because are brain has the consistency of Jell-O and it isn't strong. I picked this article because I got a concussion before and I didn't know how serious it could get, but after reading this article I hope I never get another concussion again.

    Just like any other part of the body, the brain is susceptible to injury and can greatly affect how the person with the injury goes through their daily life. As someone who has gone through multiple concussions, I can attest to just how much a brain injury, no matter how small, can upset the day to day routine. Concussions should not be taken lightly because as the article stated, they can lead to other problems later on and have long lasting effects. Despite the fact that my last concussion was over a year ago, I can still see some of the impacts of it today so take care of your brain, it's the only one you have.

    The brain swells when protective membranes tear and the flesh has room to expand, it then pushes against the skull and does lots of damage.
