- Question 3 To see the slide at the highest magnification, turn in between the 40x and 100x and add drops of immersion oil onto the slide. Carefully slide the [Select] ✓lens into position. Use only the fine focus to make the image clear.Question 13 Astigmatism is a result from a defect in the curvature of the cornea or lens sclera photoreceptors pupil sizeQuestion 6 Why do you use immersion oil with 100X objective lens? to increase image resolution to lubricate the objective lens O to make the light brighter to increase focus
- Question 12 What was needed after you use the 100 x lens? O use Chemwipe to clean the lens O use water to clean the lens O use lens paper to clean the lens O nothingQuestion 10 The blind spot is found at the fovea centralis where the vitreous humor meets the aqueous humor where the optic nerve exits the retina on the lateral side of the lensQuestion # 138 A 53-year-old man comes to the office because of difficulty reading fine print over the last year. He ow has to hold books, menus, and magazines at an arms length in order to read them. He has never had visual problems before. Which of the following is most likely abnormal in this patient? A Corneal shape B Lens elasticity C Lens opacity D Macula E Peripheral retina F Intraocular pressure
- Question 15 While viewing a slide under the microscope, I can use 100 x lens directly. O True O FalseQUESTION 9 If the scleral venous sinus becomes blocked, what condition can result due to increased intraocular pressure? myopia O colorblindness conjuctivitis glaucoma QUESTION 10 Why does your pupil constrict in the pupillary light reflex? prevent damage to photoreceptor cells under bright light conditions prevent pathogens from entering the eye protect the choroid layer of the eye prevent development of myopiaQuestion 4 What are the magnification abilities of each of the objective lenses? Scanning ( small lens ). red ring [ Choose ) Low-power ( medium lens ), yellow ring [ Choose] High-power ( large lens ), blue ring [ Choose) Oil immersion ( largest lens ), white ring [ Choose] > > > >
- QUESTION 19 The inner ear is often described as a bony as it is composed of a series of canals embedded within the temporal bone O labyrinth O entanglement O coilQUESTION 10 Why does your pupil constrict in the pupillary light reflex? prevent damage to photoreceptor cells under bright light conditions prevent pathogens from entering the eye protect the choroid layer of the eye prevent development of myopiaQuestion 2 Warning: This one is harder from a theoretical standpoint. It's okay if this one is shorter than the one above (though give it at least 100 words). Your two eyes are located on the same side of your head (the front). This helps you determine where things are in space. Your two ears are located on opposite sides of your head (left and right). This also helps you determine where things are in space. Why does having your eyes on the same side help you determine location while having your ears on opposite sides ALSO helps you determine location. Explain with reference to how the sensory cues for location work in the two senses. Hint 1: In both cases, it has to do with comparisons between the left eye/ear and the right eye/ear. Hint 2: For vision, I am thinking of depth perception. For hearing, I am thinking of left/right position.
