Hank calls in a friend to do his push ups for him today to explain how skeletal muscles work together to create and reverse movements. Hank and Claire also demonstrate the role size plays in motor units, the three phase cycle of muscle twitches, and how the strength and frequency of an impulse affects the strength and duration of a contraction. This episode also explains twitch summation, tetanus, and isotonic vs. isometric movements. Pssst. we made flashcards to help you review the content in this episode!

These videos are very well done. The amount of information presented in such a short amount of time would normally be overwhelming. The approach used works very well.

Thanks for the video! I wish I could keep up with how fast you talk, I-ve had to rewind like 50 different times to get the mental image right
