column a
a. aqueous humor
b. choroid coat
c. ciliary muscle
d. conjunctiva
e. cornea
f. iris
g. lacrimal gland
h. optic disc
i. retina
j. sclera
k. suspensory ligament
l. vitreous humor
column b

1. posterior five - sixths of middle (vascular) tunic
2. white part of outer (fibrous) tunic
3. transparent anterior portion of outer tunic
4. inner lining of eyelid
5. secretes tears
6. fills posterior cavity of eye
7. area where optic nerve exits the eye
8. smooth muscle that controls the pupil size and light entering the eye
9. fills anterior and posterior chambers of the anterior cavity of the eye
10. contains photoreceptor cells called rods and cones
11. connects lens to ciliary body
12. cause lens to change shape

complete the following:

1. list the structures and fluids through which light passes as it travels from the cornea to the retina.
2. list three ways in which rods and cones differ in structure or function.

Explanation:

Matching Section:

Each term from Column A is paired with its corresponding anatomical description in Column B based on human eye anatomy.

Question 13:

Light travels through a sequence of transparent eye structures/fluids from the cornea to the retina, following the eye's optical pathway.

Question 14:

Rods and cones differ in multiple structural and functional aspects related to vision; three key distinct traits are selected.

Answer:

Matching Answers:

1. b. Choroid coat
2. j. Sclera
3. e. Cornea
4. d. Conjunctiva
5. g. Lacrimal gland
6. l. Vitreous humor
7. h. Optic disc
8. f. Iris
9. a. Aqueous humor
10. i. Retina
11. k. Suspensory ligament
12. c. Ciliary muscle

Question 13:

1. Aqueous humor
2. Pupil (opening in the iris)
3. Lens
4. Vitreous humor

Question 14:

1. Function: Rods detect dim light (night vision); cones detect bright light and color.
2. Distribution: Rods are more dense in the peripheral retina; cones are concentrated in the fovea centralis.
3. Structure: Rods have a long, thin outer segment; cones have a shorter, tapering outer segment.
