  facts, and more just for curious kids like you.
• 0:33
  Today's episode is all about something amazing that's inside
• 0:37
  your head right now. It helps you think, feel, dream,
• 0:41
  and even move your fingers and toes.
• 0:45
  That's right, we're talking about your brain.
• 0:47
  Get ready for some super cool human brain trivia.
• 0:51
  Let's see how many answers you can get, right?
• 0:54
  Remember, after each question you'll have a few seconds to
• 0:58
  think before I reveal the answer.
• 1:00
  Let's get started. Here comes our first question.
• 1:04
  What is the main job of the human brain?
• 1:10
  The answer is the brain controls everything you do, from thinking
• 1:15
  and learning to breathing and moving.
• 1:18
  It's the boss of your whole body.
• 1:20
  Next question about how much does an adult human brain weigh?
• 1:24
  About as much as a loaf of bread, a soccer ball, or a bag
• 1:28
  of apples. The answer is a human brain
• 1:35
  weighs about as much as a loaf of bread, or around 3 lbs.
• 1:40
  That's about 1/4 kilograms. Here's another one.
• 1:44
  Which part of your body uses the most energy from the food you
• 1:48
  eat? Your legs, your stomach, or your
• 1:51
  brain? The answer is your brain.
• 1:58
  Even though it's small, your brain uses about 20% of the
• 2:02
  energy from the food you eat. Here comes a tricky question.
• 2:06
  True or false? Your brain feels pain when you
• 2:10
  get a headache. The answer is false.
• 2:17
  The brain itself doesn't have pain sensors, so it can't feel
• 2:21
  pain when you have a headache. It's actually other parts around
• 2:24
  your brain that are hurting. Time for a cool one.
• 2:28
  What is the wrinkly outer layer of your brain called?
• 2:32
  Is it the cortex, the cerebellum, or the brain stem?
• 2:40
  The answer is the cortex. The cerebral cortex is the
• 2:45
  wrinkly part on the outside of your brain.
• 2:47
  All those folds help fit lots of brain cells into a small space.
• 2:52
  Let's try this About how many brain cells does a human brain
• 2:56
  have? About 100 thousand?
• 2:59
  100 million? Or 100 billion?
• 3:06
  The answer is about 100 billion. That's more brain cells or
• 3:11
  neurons than there are stars in our Galaxy.
• 3:14
  Here's a quick one. What is the name of the gap
• 3:17
  between two brain cells where messages jump from one to
• 3:21
  another? The answer is that gap is called
• 3:28
  a synapse. Messages cross synapses using
• 3:31
  tiny chemicals called neurotransmitters.
• 3:34
  Now for something amazing, How fast can your brain send
• 3:38
  messages? Is it about one mile per hour,
• 3:42
  20 mph, or over 200 mph? The answer is over 200 mph.
• 3:54
  Brain signals can travel super fast along special cells called
• 3:58
  neurons. Let's go a little deeper.
• 4:01
  What is the part of your brain that helps you balance and
• 4:04
  coordinate your movements? Is it called the cerebellum, the
• 4:07
  hippocampus, or the medulla? The answer is the cerebellum.
• 4:17
  It's a small part of the back of your brain that helps you keep
• 4:20
  your balance and move smoothly. Here's another Which part of
• 4:24
  your brain helps you remember things and learn new
• 4:27
  information? The hippocampus, the pituitary
• 4:30
  gland, or the pons? The answer is the hippocampus.
• 4:40
  It's shaped a bit like a seahorse and is super important
• 4:43
  for memory. OK, here's a fun one.
• 4:46
  Is your brain more active when you're awake or when you're
• 4:49
  asleep? The answer is your brain is
• 4:56
  actually very active when you're asleep.
• 4:59
  It does important jobs like sorting memories and helping
• 5:02
  your body grow. Let's try something about your
• 5:05
  senses. Which part of your brain helps
• 5:07
  you see? Is it the occipital lobe, the
• 5:10
  frontal lobe or the temporal lobe?
• 5:17
  The answer is the occipital lobe.
• 5:20
  It's at the back of your brain and helps you process everything
• 5:24
  you see. Ready for another?
• 5:26
  What percentage of your brain do you use?
• 5:29
  10 percent, 50%, or almost all of it?
• 5:37
  The answer is you use almost all of your brain.
• 5:41
  The idea that we only use 10% is a myth.
• 5:44
  Now for a smell question, which part of your brain helps you
• 5:48
  recognize smells? The olfactory bulb, the brain
• 5:51
  stem, or the amygdala? The answer is the olfactory
• 6:00
  bulb. It's at the front of your brain
• 6:03
  and helps you notice and remember different smells.
• 6:06
  Here's a quick one. What is the largest part of your
• 6:09
  brain called? The cerebrum, the thalamus or
• 6:13
  the hypothalamus? The answer is the cerebrum.
• 6:21
  It makes up most of your brain and is responsible for thinking,
• 6:25
  speaking, and decision making. Here's a challenging one.
• 6:30
  What is the thick bundle of nerves that connects the left
• 6:33
  and right halves of your brain called?
• 6:35
  Is it the corpus callosum, the spinal cord, or the optic nerve?
• 6:44
  The answer is the corpus callosum.
• 6:48
  It lets the two sides of your brain talk to each other.
• 6:51
  Time for a fun fact. Can your brain grow new
• 6:54
  connections when you learn something new?
• 6:57
  Yes or no? The answer is yes.
• 7:05
  When you learn, your brain grows new connections between brain
• 7:09
  cells, which helps you remember. Let's talk about reflexes.
• 7:13
  What part of your nervous system controls quick reactions like
• 7:17
  pulling your hand away from something hot?
• 7:20
  Is it your brain, your spinal cord, or your heart?
• 7:27
  The answer is your spinal cord. It handles fast reflexes before
• 7:32
  your brain even knows what happened.
• 7:35
  Here's another cool question. What is the name for the folds
• 7:39
  and bumps on your brain surface? Are they called gyri and sulci,
• 7:43
  lobes or ventricles? The answer is gyri and sulci.
• 7:53
  They make your brain surface look all wrinkly and help fit
• 7:57
  more brain power into your head. Let's try a taste question.
• 8:01
  Which part of your brain helps you taste food, the temporal
• 8:04
  lobe, the insula, or the occipital lobe?
• 8:11
  The answer is the insula. It's deep inside your brain and
• 8:16
  helps you taste and enjoy your food.
• 8:19
  Here's a memory question. When you remember your first day
• 8:22
  at school, which part of your brain is working hard?
• 8:25
  The cerebellum, the hippocampus or the brain stem?
• 8:34
  The answer is the hippocampus. It's especially important for
• 8:39
  remembering events and facts. Ready for one about growth?
• 8:43
  Which tiny part of your brain controls hormones and helps you
• 8:46
  grow? The pituitary gland, the
• 8:49
  medulla, or the thalamus? The answer is the pituitary
• 8:58
  gland. It's sometimes called the master
• 9:01
  gland because it helps control growth and other hormones.
• 9:05
  Here's a language question. Which side of your brain is
• 9:08
  usually more active when you speak or right, Left or right?
• 9:16
  The answer is the left side. For most people, the left side
• 9:21
  of the brain controls language skills.
• 9:23
  Let's finish with something amazing your brain is made
• 9:28
  mostly of what? Bone, muscle, or water?
• 9:36
  The answer is water. About 75% of your brain is
• 9:41
  water, which is why it's important to stay hydrated.
• 9:45
  And now it's time for today's super challenge question.
• 9:49
  This one is extra tricky, so get ready.
• 9:52
  What is the longest cell in your body and how does it connect to
• 9:56
  your brain? The answer is the longest cell
• 10:04
  in your body is a motor neuron. Some motor neurons stretch all
• 10:08
  the way from your lower back to your toes, sending signals from
• 10:12
  your brain and spinal cord to your muscles.
• 10:15
  Thanks for playing along with today's human brain Trivia.
• 10:18
  Whether you got every answer right or learned something new,
• 10:22
  you just gave your brain a great workout.
