Muscles & Bones (Year 5 only)


Muscles & Bones

Chorus

When you nod your head,
Manoeuvre the cranium,
Or stamp your feet,
Twenty-six bones each,
When you clap your hands,
A clash of the phalanges,
There’s a lot going on underneath.
O, the skin is a fabulous thing to be in,
But it can’t get round on its own.
Every action needs a muscle contraction
And a lot of support from your bones.

Verse 1
Now the average newborn baby has over 300 bones,
And then some will fuse together on the way to being totally grown.
So the average adult human has only 206,
But there are still enough of them to hold you up
And do some pretty impressive tricks.
The longest is the femur, in the thigh is where you’ll find it;
The strongest is the tibia, and the fibula is behind it.
Oh, it’s great to know you’re a vertebrate, it’s divine to have a spine,
So let’s celebrate the fact that our backbone’s stacked
And give it ten out of nine for design.

Chorus
Verse 2

You’ve got more than six hundred muscles
And they always work in pairs.
There are even very small ones
At the root of every one of your hairs.
When you’re sitting down watching telly,
When you’re sitting on top of the bus,
The very bottom line
Is that you’re spending time
Upon your gluteus maximus.
Your mum might wag her finger
If you accidentally vex her,
In other words,
She’s exercising a warning digital flexor.
We depend on muscles and tendons too,
And it makes you stop and think….
It takes seventeen to smile,
Forty three to frown,
And slightly over one hundred to wink.

Chorus
