Question
The image contains text from an educational document, including two tables and associated activity questions related to muscle stimulation experiments. **Chart 1: Effect of Stimulus Voltage on Active Force** | Voltage (V) | Active Force (g) | |-------------|------------------| | 0.0 | 0.0 | | 0.2 | 0.0 | | 0.4 | 0.0 | | 0.6 | 0.0 | | 0.8 | 0.0 | | 1.0 | 0.0 | | 1.5 | 0.0 | | 2.0 | 0.0 | | 2.5 | 0.0 | | 3.0 | 1.8 | | 3.5 | 5.0 | | 4.0 | 7.0 | **Activity Questions:** 1. For a muscle like the one in this lab, explain the effect of increasing stimulus voltage. 2. How is this effect on a muscle achieved in vivo (in the body) [with the excitability of neurons]? **Activity 3: The Effect of Stimulus Frequency on Skeletal Muscle Contraction** - This section instructs users to return to a PhysioEx menu and select activity 2 before starting. - The experiment involves increasing the frequency of stimulus voltage to determine its effect on muscle force generation. - Users will follow directions starting on page 23 of the PhysioEx guide for specific instructions. **Table: Effect of Stimulus Frequency on Active Force** | Voltage (V) | Frequency (Hz) | Active Force (g) | |-------------|----------------|------------------| | 8.5 | 50 | | | 8.5 | 60 | | | 8.5 | 90 | | | 8.5 | 110 | | | 8.5 | 130 | | **Activity Questions:** The document instructs further exploration into the effects of increasing stimulus frequency, suggests a limit to the response, and refers to enhanced muscle simulation in a human body context. Users are encouraged to complete the tables by conducting the experiments as described in the guide.
