bill nye the science guy s02e08 Bones & Muscles

[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
