To quiz yourself on muscles, select the Quizzes option from the Home screen and choose a muscle group from the list. An interactive 3D View of the area will appear with relevant musculature displayed, along with a series of prompts in a window at the bottom of the screen.
The quiz will prompt you to identify structures in the View. To answer a quiz prompt, tap the correct structure in the View and select Submit. If your answer is correct, you can press the "Next" button to move on to the next item.
If you submit an incorrect answer, you are given the choice to tap "Next" and move to the next prompt, "Highlight," or "Try Again." Selecting "Highlight" highlights the correct structure in the View. "Try Again" gives you another chance to guess the correct structure. You are given three tries for each question. The number of tries remaining is shown in parentheses next to the prompt.
In a Quiz View, you can adjust the 3D model just like in regular views. Zoom in or out to see the model more clearly; tap on structures to select and show/fade/hide, or rotate the model using your fingertips. Adjusting the model can be helpful in identifying structures correctly, especially when they are small or partially hidden by other anatomy. You can refresh the View at any time using the Refresh View button on the left of the screen.
At the end of the quiz, you will be shown the number of questions you answered correctly and incorrectly. Tap "OK" to exit. You can end the quiz at any time by tapping the X button in the top left corner of the quiz window at the bottom of the screen. Quitting the quiz transforms the Quiz View into a regular 3D interactive View. From here, you can study the muscle group further, select another quiz by tapping Menu, or choose another option by returning to the Home screen.
