Study Activity

Perform the study activity below:

Use the Muscle Stimulation Virtual Lab to experiment with muscle tissue. The goal of this lab is to determine what stimulus is necessary for different types of frog muscle tissue to respond under different levels of stress. Read through the procedure and follow the instructions to experiment with the four types of muscle. Use a notebook if necessary to take down your data. You do not need to use the tools on the website.

  • Which type of muscle requires the least stimulus when unstressed (0 g; no weights)?
  • Which type of muscle requires the greatest stimulus when unstressed?
  • What is the most mass each muscle type can lift at a voltage stimulus of 10 V or less?
  • What can you conclude about types of muscles found in different parts of the body?
