Question 1

Sclera

Answer 1

The outside layer of the eye, which is white fibrous tissue (Protects the eye

Question 2

Cornea

Answer 2

Transparent part of the outside layer of the eye. Protects the eye and allows for light to bend

Question 3

Aqueous Humor

Answer 3

Made up of water and salt and helps maintain pressure within the eye and providesnourishment to the cornea and lens

Question 4

Iris

Answer 4

A ring-shaped muscular membrane located behind the cornea, this determines a person’seye color and controls how much light enters the eye

Question 5

Pupil

Answer 5

The dark part of your eye, located between the iris. This is where light will pass through upon entering the eye

Question 6

Lens

Answer 6

Allows for the eye to change focus, located behind the pupil and iris

Question 7

Vitreous Humor

Answer 7

Clear gel-like fluid in the vitreous cavity. It gives the eye support and shape

Question 8

Retina

Answer 8

Located in the back of the eye and is made up of layers of light sensitive cells, known as photo receptors. Which convert the light into neural impulses that allow for the brain to process what the eye is seeing

Question 9

Choroid Layer

Answer 9

Blood vessels that help keep the retinal cells and the other cells in the eye healthy by providing oxygen and nutrients from the blood vessels, also absorbs stray light

Question 10

Optic Nerve

Answer 10

Located in the back of the eye, it is made up of the retinal ganglion axon, neural impulses travel in the optic nerve from the eye to briefly stop at the thalamus, then travel to the primary visual cortex where the information will be processed in the occipital lobe

Question 11

rods vs cones

Answer 11

Cones are what help you see fine details, allow you to have clear vision, and allow you to see color. Rods are visual receptors that allow you to see in dim light

Question 12

Identify what is located in front of the rods and cones and describe their function

Answer 12

Cones are what help you see fine details, allow you to have clear vision, and allow you to see color. Rods are visual receptors that allow you to see in dim light

Question 13

astigmatism vs cataracts

Answer 13

Astigmatism happens if the cornea is irregularly shaped and could impact a person’s ability to focus. While cataracts happens when the lens of your eye becomes cloudy, causing vision to become blurry

Question 14

Trichromatic theory and opponent-pressing theory

Answer 14

Trichromatic theory states that individuals are able to see color because different wavelengths of light stimulate combinations of three color receptors.(Photoreceptors work in teams of three, red, green, and blue) While the opponent-processing theory compliments the trichromatic theory. Here information that is received from the cones is sent to ganglion cells, this causes some neurons to become excited and others inhibited.

Question 15

What colors have a longer wavelength and which ones have a shorter?

Answer 15

Cooler colors have a short wavelength and warmer colors have a longer wavelength.

Question 16

Achromatism

Answer 16

People can only see black, white, and gray because they lack retinal cones

Question 17

Dichromatism

Answer 17

Individuals possess only two or the three types of retinal cones. Which leads to confusion between certain colors. Most common type is red-green color blindness

Question 18

Trichromatism

Answer 18

Individuals with the ability to see all of the colors

Question 19

How does synesthesia impact a person?

Answer 19

This is a neurological condition where when one of an individual’s senses is stimulated it will result in stimulating another sense at the same time
