Question

use the following information to answer question 9.

1. match the labelled eye structure with the correct eye condition or eye function. place the correct number on each line. use each number only once.

astigmatism occurs as a result of a disorder associated with this structure 1. structure b
captures stray light; contains nourishing blood vessels 2. structure l
contains a high concentration of cones 3. structure c
glaucoma results if this fluid is not drained properly 4. structure i
contains the photoreceptors; rods and cones 5. structure f
sensory neuron to the brain 6. structure j
the blind spot; no photoreceptors found here 7. structure k
cataracts can develop in this structure 8. structure m
hint: the pupil (letter d) is not a structure. it is a space. because letter d is the pupil, please do not use this letter for aqueous humour.

Explanation:

Astigmatism is due to an irregularity in the cornea (Structure B). The choroid (Structure L) captures stray light and has nourishing blood - vessels. The fovea (Structure I) has a high concentration of cones. Glaucoma is related to improper drainage of aqueous humor (Structure F). The retina (Structure J) contains rods and cones. The optic nerve (Structure M) is the sensory neuron to the brain. The optic disc (blind - spot) is Structure K. Cataracts develop in the lens (Structure C).

Answer:

astigmatism occurs as a result of a disorder associated with this structure - 1. Structure B
captures stray light; contains nourishing blood vessels - 2. Structure L
contains a high concentration of cones - 4. Structure I
glaucoma results if this fluid is not drained properly - 5. Structure F
contains the photoreceptors; rods and cones - 6. Structure J
sensory neuron to the brain - 8. Structure M
the blind spot; no photoreceptors found here - 7. Structure K
cataracts can develop in this structure - 3. Structure C
