[Verse 1]
One neuron wakes, one wire down the spine,
Alpha motor calling, every fiber in line,
It's not a crowd of bosses, just a single command —
One cell, one order, the fibers understand.
Every fiber's loyal to a single master's voice,
No fiber serves two masters, that's the muscle's only choice,
This whole arrangement's got a name, so hear it, hold it tight —
Motor unit's the engine turning thought to bite.
[Chorus]
Один нейрон — много волокон,
One neuron, fibers by the score,
Final common path, Шеррингтон знал,
Every signal walks through this one door.
Моторная единица, помни её суть,
Nerve and fiber bound as one — that's the only route.
[Verse 2]
Look into an eyeball, count the fibers there,
Only ten per neuron, such precision, such care,
Tiny moves, fine control, the eye darts quick and neat —
Now go down to the calf where the gastrocnemius beats,
Two thousand fibers bowing to a single alpha's call,
Innervation ratio — low for precise, high for raw and tall,
Small ratio buys you finesse, big ratio buys you power,
Same wiring rule, different fibers by the hour.
[Chorus]
Один нейрон — много волокон,
One neuron, fibers by the score,
Final common path, Шеррингтон знал,
Every signal walks through this one door.
Моторная единица, помни её суть,
Nerve and fiber bound as one — that's the only route.
[Verse 3]
Type one is slow and steady, fatigue-resistant, true,
Marathon fiber, red and patient, never says "I'm through,"
Type two-A, fast fatigue-resistant, the sprinter who can stay,
Type two-B, fast fatigable, explosive, gone away,
Burns bright and quick then quits the scene, a firework in the dark,
Three fibers, three personalities, each leaving its own mark.
[Verse 4]
Small units first, that's the order, the size principle's law,
Little alphas fire easy, the first to answer the call,
Then the bigger neurons join when the force demands more weight,
Recruitment climbs the ladder, precise and never late,
Henneman knew the pattern, smooth control from weak to strong,
Gradual power building — that's how the body sings its song.
[Bridge]
Calcium spills from sarcoplasmic halls,
Actin and myosin answer the calls,
Cross-bridges grab, they ratchet, they slide,
Filaments sliding side by side —
Это скольжение нитей, сила родилась,
Sliding filaments, the muscle's secret pulse.
[Chorus]
Один нейрон — много волокон,
One neuron, fibers by the score,
Final common path, Шеррингтон знал,
Every signal walks through this one door.
Моторная единица, помни её суть,
Nerve and fiber bound as one — that's the only route.
[Outro]
Cortex, reflex, every route converges here,
Through the alpha neuron, the message rings clear,
Последний общий путь — the final common gate,
Muscles and motor units — that's the brain's blueprint, that's the fate.
