[applause] Ok, Ok, yea I have to take care of this now
How are you doing Mr. Marrow, sorry I'm late
there was a lot going on in the lab. Boy
Mr. Marrow are you getting enough exercise for
your muscles? It's like you're all bone. Mr. Marrow? Mr. Marrow? Mr. Marrow? NOOOOOOOOOOOOOOO!
Bill Nye the Science Guy, Bill Bill Bill Bill Bill Nye the science guy. Science rules!
Bill Nye the science guy. Ernicia is a property of matter.
Bill Bill Bill Bill Nye the science guy. T minus 7 seconds
Bill Nye the science guy. bRought to you by bones without them you wouldn't have a leg to
stand on. bones and muscles available in fine animals everywhere
do you realize to work these buttons and open
this door I need every muscle and bone in my body
that's because they're all working together
whether your waving, walking, walking funny
running, jumping, or flying your muscles and bones work together
to make you move. see there's a skeleton in
every one of us. we're all a bunch of bones
this is our extension arm of science. This
white pieces are like bones and these thin ropes are like
muscles. now watch what happens when we make this rope
this muscle shorter. the arm moves this way
we make this rope shorter the arm moves that
way. see hoo, haw hoo haw hoo haw hoo haw hoo haw
no matter which way pushing or pulling the muscles are getting shorter
they are contracting. Now we have 200 bones on our body
most of them are controlled with two sets of muscles
that's what allows us to move and jump and
hoo haw. Bones form the framework of our body
ligaments help hold the bones together muscles move the bones
tendons anchor the muscles to the bones.
AHHHCHOO. you have tendons all over your body
as you can see the tendons in the back of your
hands. those tendons connect these muscles
with these bones. Isn't that cool? Oh, I've
gotta go. Whats the breakfast treat that
sure to please from your pirital bone to your
flanges. Bone-os, bone-os. Here's a very
cool experiment that you can do to prove that
bones have minerals. Next time you eat
chicken or turkey save the bones. Take a leg bone
it's the biggest bone and put it in a bowl of
vinegar. We're wearing safety goggles becauase
vinegar is an acid. Leave the bones in for a long
time after 2 months. The acid dissolves all the
mineral away from the bone. Without minerals
the bones get soft and easy to bend. You can
even tie one in a knot. There. [applause]
hammering looks simple doesn't it? You just
move your arm, but watch the hammer needs your
fingers and they are connected to your wrist
and that's connect to your lower arm and that's
connected to your upper arm and that's connected
to your back and that's connected to your
leg. Look you even need to move your toes to hammer. To even
do a simply thing like this you need your whole
body because your bones and muscles are connected.
Oh, oh ouch ouch. [ominous music] what is that
over there what is that thing? Ohhh It's the
science guy! Scared you huh? See sharks don't have
any bones they're all cartilage soft and rubbery. You have cartilage too in
your ribs, your ears, and your nose. See how soft it is and rubbery.
What? [music]
Without bones, we couldn't hold ourselves up.
We'd be floppy, like this pancake. We'd just collapse.
On the other hand, if we're all stiff rigid bone, like this
gingerbread guy then we couldn't move at all we need
muscles and soft movable parts to get around
muscles move our bones around. That's how it works, whether you're lifting something
pushing, or jumping up like a spring, ha ha
muscles and bones help us move around. coming this
sunday its the muscle pull. smooth striped and caridac
we've got it all! Muscles, muscles, and more muscles
extending and contracting and moving like
you've never seen before! So grab the kids
grab the dog and grab the neighbors and grab your ace bandage
and come on down to the anatomy arena!
muscles move our bodies. without muscles we couldn't ride a bike.
or play with dogs [Man: Uh, Bill] or do experiments in the lab.
[Man: Bill] so our muscles help us move
because they all work together [man: your not fooling anyone Bill.]
So as i move the muscles in my arm my biceps
i'm also moving all the other muscles in my body
because they're all connected
bones! [man: Bill, uh Bill] Muscles!!
Those are very fine muscles you have. Of
course you know these muscles are very important
they give you the power to move about to do the work in the fields.
now if we can look inside of you we can see
the skeleton, the bones of your body. why do you
have these bones? The best way is to take away the skeleton and see what happens.
look out! down you go you see you really need that skeleton
that's the framework that holds your body up.
Did you know that teeth are the strongest
bones in the skeleton. There are 3 bones
in the ear, the hammer, the anvil, the stirrip. There are over 600 separate muscles in the body.
now you know!! Our bodies are like machines.
or machines are a lot like our bodies. when
a mechanism moves they have joints. like this
door has a hinge. we have hinge joints in
our fingers and our jaws. Ahhhhhh!
[skeleton: Hello there Bill] our bones and muscles
let us move our joints. Please consider the
following.
So in our hand, we have hinge joints. Like the
hinges on a gate. Also in our hands we have a
special joint called the saddle joint, in our
thumb. It allows our thumb to go this way
or this way. 2 directions 1 joint. cool!
also in our body we'll find ball socket joints
the kind we see in a tv. Ball and socket joints
in our body are in our hips. look at our
hips move in all different ways.
In our backs, we have swervy joints a whole bunch of them. Our backs slide
theres in joints in our body that don't move at all.
fixed joints. There's fixed joints in your skull, but they don't move. all the
different joints in our body let our bodies move
all different ways. Thanks for joining me
I mean joint-ing me on consider the following.
introducing a collection of music so spine
tingling it can be brought to you only by
Deutsch gramabone. Presenting bonely is the night.
who can forget songs like, Tiba tiba tibula, how i love my tibula.
my leg bone and me. If I din't have a spine I couldn't stand it. Because I couldn't stand!
Yo cranium, clavicle, and sternum you've got
you got over 200 bones why don't you learn them. All these and many many more
you realize what you're doing, don't you?
Yea, I'm cracking my knuckles in your face.
Actually you're pulling your bones apart and letting air
bubbles between your joints. I am?
I'm Tim Eng I work for Nike sport research
lab and we have fun here and try to find
the science behind the shoes.
Big part of my job is learning how to distribute
the pressure beneath the foot to minimize the
impact and shock up into the bones and muscles
with the bare foot we can see how much pressure
is beneath the heel, the ball of the foot and
the big toe. with a well design shoe we can
distribute the pressure over the foot so that
we can absorb some of the shock that goes
through the bones and muscles of the legs.
with the shoe we can see the high pressure
beneath the heel are gone and force of pressure
is distributed evenly. good shoes fewer
injuries!
Bile Nye!!! it's easier to smile than it is
to frown. That's because you only need
17 muscles in your face to smile, but it takes
43 muscles to frown. Ouch! that was my foot!
You never knoww when you're going to need more energy, less energy to smile! See ya!
Did you know that...a sparrow has more bones in it's neck
than a giraffe does. The largest bone ever
found was the 7 ft long brachiosaurus arm bone.
Birds have hollow bones, which are light, so they can fly.
Now you know!! ladies and gentlemen, I
present the bone. Although bones come in all different shapes and sizes, they
are basically the same 3 things. On the outside
is a hard membrane called the periosteum,
and underneath that is a layer called the compact bone. that's the layer a dog really likes.
then on the inside the soft cancellous bone
sometimes called the spongy bone. see dogs
aren't into sponges, but dogs do like bones
Bones are apart of you, part of what keeps you
kicking. and kicking, part of what keeps you
kicking. Nice job! I got a bone to pick with you. When you're born you have
about 350 bones. There not all bones,
there's cartilage, that's what your ear is made of, and your ears.
anyway cartilage fuses together to make bones
your skull starts as several different plates and ends up as 1 big bone.
So by the time your my age you only have
200 bones. But you started out with 350, isn't
that wild. hey listen i'm not pulling your
femur. that's a bone gag. she loves those bones jokes, don't ya.
oh please. to the bone mobile.
[Moo] Hey, leave that cow alone. I'm bone
boy! but i was going to milk it. then you
know that milk is a strong source of calcium. I'm bone boy!!
Ahh calcium. [tink tink on glass] Milk is a
good source of calcium and other minerals
is what help make your bones so strong.
here's a t-bone from a t-bone steak and here's
a piece of aircraft aluminum
you hold them like this they have the same
sizes and shape, which one is stronger
take a look, we've mounted them both on this
t-stand of science. t-bone, t-stand, haha let's
put some heavy weights on them. this would
be a couple of liters of heavy soft drink.
they both bend down about the same amount.
that's not all there is to having bones
you playing soccer and get hit in the ribs in the t-bone
watch, we'll simulate getting hit in the bone
with this pair of plyers, t-bone pretty strong
aircraft aluminum not so strong. see it a
good thing you're made of bone.
a real good thing. milk a strong source of
calcium. I'm bone boy.
wrestling has a lot of do with balance and
strength, speed, agility and moving joints the
wrong way. It's a lot of fun!
Now what? By doing this bending the knee joint the opposite way
Elbows bent like this by putting more pressure
on it the joint, it'll pull away from the
shoulder and causes him to have pain.
wrestling is painful, but it's fun!
I win!
Your back bone isn't 1 single bone, it's
actually 33 small bones stacked on top of each
other. small bones are called vertebra
and they're hollow they protect your spinal
cord the bundle of nerves that run down
your back. Now the spinal column supports
your whole body. a bunch of gliding joints
they glide on each other because each vertebra
separated by a soft squishy disk called cartilage.
the same stuff you have in your nose.
so your spinal column has a whole bunch of gliding joints. that's what makes you flexible.
you can i have 33 vertebra a big snake like thi
has over 400. thats why snakes are so
flexible. you know Mr. Python that's a great
looking backbone. A great looking set of back bones.
it's really nice. Mr. Python, Mr. Phython, Mr. Pyyyython.
They came from the spindarosa bone-anza!
So little Joe I aint what you call fat am I?
I'm just big boned, right? Yea, big boned, that's what you are.
actually there really no such thing as big
boned. most humans have the same bones in the same size.
so my bones they are about the same size as his. buy guys like Hass
you know how sensitive they can be. Yup, big
boned that what I am. Yea, big boned
Did you know that...muscle makes up 85% OF YOUR
body weight. a human skeleton starts out as
cartilage that hardens into bones over your
entire lifetime. Bones is stronger inch to inch than skyscrappers. Now you know!
our bones move in different ways because they're all connected by joints.
they all work together so we can do things like this.
Got bones in my body, or else i'd be like
jelly. they help me stand up staight so i can
perform ballet. yea, i got bones in my body
working with my muscles too. they let me do my
ballet and how about you. like a true burn brake i think bones bones are great, they
work with muscles too they're in me and you! bones in my body!
bones in my body! thanks for muscling in to
see this show. it sent chills up my spine. if you
excuse me I need to bone up for the next
show. produced in association with the national
science foundation. what? it's the fin isn't it.
your bones are connected to your muscles and
the 2 of them working together will allow you to ride your bike up this hill.
see the stiff bones are connected to the soft
muscles. Race ya! Fools, they laughed at
me. i use bones and muscles to answer the
phone, small world huh? Alien boy, love ya. that was my mom
