Simersong #7 Wonder in Me (The Muscle Contraction Song)

Simersong #7 Wonder in Me (The Muscle Contraction Song)


We write devices mnemonic,
so the professors won’t think you’re moronic. Learn Simersongs, and you’ll do us proud,
singing tunes while taking tests, but not out loud! The “pair-a-docs” is back, and our mermaid
here has a little dilemma. Yeah, I’m tired of swimming. I wanna dance! Ooo, you need skeletal muscles for that . . .
not to mention legs. I’ve got those! Ooo, check out those gastrocnemii! Here’s a little song to help you work those,
mon. The membrane is always keener
beyond the synaptic gap Vesicles, when stimulated,
release ACh ASAP. Then all that acetylcholine
opens channels in the endplate. When sodium diffuses inward,
depolarizations we create! Wonder in me—
How can it be that a simple thought
makes my muscles taut voluntarily? Fibers contract and then relax:
An awesome act; just check the facts! Can’t help gyrating
‘cause I’m celebrating this wonder in me! The action potential’s happy
as over the cell it rolls. It spreads until it encounters
the holes called T-tubules. The signal, it plunges downward
toward the center till it finds calcium stored in cisternae,
released so troponin, it binds! From cisternae, term’nal cisternae, comes the calci-ion who stick like fly on troponin-C! It rolls tropomyosin away, so myosin heads grab actin–Hey! They’re power strokin’. They need (no jokin’) your ATP! Wonder in me! Wonder in me! Lets every sarcomere work with a spark o’ cheer naturally! But what is this? Doubt on your face? Well, we can’t stop till we’ve made our case! Here’s how we’ll do it: we’re gonna review it! [Both:] This wonder in me! The brain start the game
Neuron and axon Can’t trace ACh
‘Cause, mon, it be gone! Synapse be the gaps
The boss gotta cross To dock and unlock gates wide! (Yeah!) Endplates open gates
To free the AP Which drop to a stop
At the cisternae! Out come calcium
Which spin troponin To clear sarcomeres to slide! [Interlude] What are those guys doing here? Ah, they don’t have their own production number in their movie. Let them join in! Wonder in me! [Fish chorus:] Wonder in me!] Now I can see . . .
[Now I can see . . . ] how a simple thought
makes my muscles taut voluntarily! [ee, ee, ee, ee!] Fibers contract and then relax. It’s an awesome act; we’ve learned the facts! [Both:] Can’t help gyratin’
‘cause we’re celebratin’ [All:] this wonder in me! So well designed here,
it blows your mind here! [All:] This wonder in me! Lose no detail here,
and you won’t fail here. No need to feel blue
‘cause it’s in you, too! [Both:] Yeah, we amazed here,
and a bit crazed here! [All:] Wonder in me-e-e-e-e-e-e-e-e-e-e! [Sebastian:] Jumpin jellyfish! Don’t forget dat cool tie, now! [Theme plays.] [Sebastian:] Oh, mon! Gotta sing me another Simersong! Heh-heh-heh.
