`` Itch! ITCH! Heads up boys, we've got to move!'' the neuron shouted. `` Move!'' `` Move!'' `` Move!'' Its neighbors echoed.

 `` Got ta go! Got ta release the calcium! Calcium!'' Bellowed the motor end plate. This echoed deep into the tubules of the muscles, opening a hatch. And out poured the calcium like a tidal wave of stress balls, filling every nook and cranny. Troponin, holding its friend Tropomyosin in a bear hug, released its grip to catch a few. Tropomyosin got up and stretched. 
 
 Almost immediately, Myosin noticed that a seat was available, and sniped it like an asshole. Tropomyosin, still blissfully stretching, remained unaware. Myosins all over followed suit, settling deep into the actin chairs and scooting around. The walls shook, creaked, and groaned like a centuries old machine.
