  • Hi everyone! Do you guys know how scientists determined why our muscles move the way they do?
  • IB BIOLOGY YEAR 1 Christopher Myers
  • No, where did their research originate?
  • Not exactly but I've read somewhere that it came from an animal, is that true?
  • Yes that is true! Researchers determined why our muscles move the way they do from jellyfish!
  • Cool! How did they do that?
  • In addition, researchers use fluorescent dyes to measure the movement of Actin and Myosin which are the myofibrils of the muscle fiber.
  • Jellyfish have a protein called Aequorin which is associated with the green flourescent protein you sometimes see on jellyfish!
  • Aequorin binds with Calcium 2+, just like how Calcium is released in a human muscle fiber through the Sarcoplasmic Reticulum when there is a stimulus.
  • I bet that the fluorescent dye is important to measure the fast movements of a muscle fiber.
  • Wow! I never knew that!
  • Thank you!
