Friday Fun: Five Gross and Goofy Body Facts

  • When something stinks, you use muscles to wrinkle your nose. Muscles inside your nose sniff sweet scents—and nasty ones, too. And when you have a cold, they blow out slimy snot and crusty boogers.
  • When your sister tells a lie, you use muscles to raise one eyebrow. When the sun is too bright, you squint your eyes.
  • When you want to whistle a tune, you purse your lips. Muscles around and inside your mouth help you, too. You use them to talk, chew food, and stick out your tongue.
  • Six muscles work together to move your eyeballs up and down, right and left. And more muscles inside your eyeballs help you see.
  • Dozens of muscles take turns contracting and relaxing to tell other people how you feel. You use them to smile, scowl, and frown; to look scared or surprised; and to make goofy faces.
