How does your brain know to wake up when you need to go to the toilet?
Question:
Answers:
i'll put this in basic terms.
you have nerve sensors in your bladder. when your urine level reaches a certain point, these nerves fire off an electrical signal to your brain that triggers the urge to urinate and wakes you from your sleep.
pretty basic (i could have written like 4 paragraphs to explain that!!) but pretty cool huh?!
because your body tells it to. Having said that, I normally don't need to go until I'm up anyway.
your bladder transmits the information to the brain that it is full
put very simply that is the answer
We call that neurons, meaning they are the nerves that sends signals to the brain about the feelings we get and identifies them, then it send more signals back to our body to do what is necessary like waking up to release the fluids stored in our body by urination..
Maybe not always. Here's the story of Dave the hen!
Dave came home from the pub late one Friday evening stinking drunk, as he often did, and crept into bed beside his wife who was already asleep. He gave her a peck on the cheek and fell asleep. When he awoke he found a strange man standing at the end of his bed wearing a long flowing white Robe.
"Who the hell are you?" demanded Dave , "and what are you doing in my bedroom?" The mysterious man answered "This isn't your bedroom and I'm St Peter "
Dave was stunned "You mean I'm dead!?!! That can't be, I have so much to live for, I haven't said goodbye to my family. . . you've got to send me back straight away."
St Peter replied "Yes, you can be reincarnated but there is a catch. We can only send you back as a dog or a hen." Dave was devastated, but knowing there was a farm not far from his house, he asked to be sent back as a hen. A flash of light later he was covered in feathers and clucking around pecking the ground.
"This ain't so bad" he thought until he felt this strange feeling welling up inside him. The farmyard rooster strolled over and said "So you're the new hen, how are you enjoying your first day here?" "It's not so bad" replies Dave , "but I have this strange feeling inside like I'm about to explode." "You're ovulating" explained the rooster, "don't tell me you've never laid an egg before?" "Never!" replies Dave . "Well just relax and let it happen" So he did and after a few uncomfortable seconds later, an egg pops out from under his tail. An immense feeling of relief swept over him and his emotions got the better of him as he experienced motherhood for the first time. When he laid his second egg, the feeling of happiness was overwhelming and he knew that being reincarnated as a hen was the best thing that ever happened to him
. . . . . . Ever!
The joy kept coming and as he was just about to lay his third egg he felt an enormous smack on the back of his head and heard his wife shouting.......
" Dave , wake up you drunken bast*rd, you've sh*t the bed."
I don't know. I just thank God I do wake up.
My brain was a wee bit slow on this one!! I used tae pee the bed, had alarms, strange dreams aboot going fur a pee. The only thing that stopped me wetting the bed was when my parents bought me a new mattress(they wurr offy poor) and I suddenly stopped. I still huv weird dreams aboot huvvin' a pee, but seem tae be able tae wake up and dive tae the bog! Good luck!
there is a cell in your brain that tellls you when your bladder is full,thats why a lot of children pee the bed,theirs is not developed fully..
nerves in the bladder tell your brain you need to go
