### Labeling Activity

**A.** The figure below represents a single muscle twitch.

#### Diagram Explanation

- The graph demonstrates the phases of a muscle twitch, consisting of points labeled from **1** to **5**.
  - **1**: Represents the onset of the stimulus.
  - **2**: The beginning of muscle contraction.
  - **3**: The peak of contraction.
  - **4**: The relaxation phase.
  - **5**: The return to baseline.

**B.** Label each section of the graph below as either tetanus, twitch, or summation. Then give an explanation of what is happening in terms of stimulus frequency and force of contraction.

#### Diagram Explanation

- Below the graph, stimuli are marked by arrows along the x-axis (time in seconds).
- **6**: A single twitch response due to a single stimulus.
- **7**: Shows summation, where multiple stimuli before complete relaxation cause increased force.
- **8**: Tetanus, where rapid stimuli lead to sustained contraction without relaxation.
