  1. I disagree with the answer you have posted for question 3 on Quiz 1. The AMOUNT of light entering the eye is controlled by the iris. Is it not?

  2. good test

  3. very helpful

  4. its a very good star and very helpful for the ABO test. I do agree with Kathy on question#3.

  5. It’s truly a nice and helpful piece of information. I am glad that you shared this useful information with us. Please keep us up to date like this. Thank you for sharing.

  6. You marked me wrong on question 3.I believe I answered correct that the amount of light entering the eye is controlled by the Iris not the pupil. The Iris has 2 muscles, the dilator and the sphincter that have the ability to change the pupil size that controls the amount of light that enters.

  7. I agree with the test takers that have a problem with the way you marked questions 3 as incorrect. The iris muscles DO control the constriction/dilation of the pupil.

    • Fixed. Thanks for the correction.

  8. Quiz #2 is missing.

  9. these quizzes have been very helpful. thank you!

  10. The 6 muscles of the eye.I have index cards that say;1.Temporal Retus 2. Nasal Retus 3.Superior Retus 4.Inferior Retus 5.Superior Oblique 6.Inferior Oblique but,on number 10 it shows to be different.Have they changed it to Lateral Retus and Medial Retus.Just wanting to know because I keep getting it wrong.I have 1 more day till test.I am so excited.Thank you again.Della
