Question 14

Three tunics of the eye

Answer 14

Fibrous (outer)
Vascular (many blood vessels)
Nervous ( inner with many neurons)

Question 15

Sclera

Answer 15

In fibrous layer
White of eye
Protects + attachment for muscles

Question 16

Cornea

Answer 16

In fibrous layer and transparent

Question 17

Choroid

Answer 17

In vascular layer
brown membrane lining the Sclera
Absorbs light

Question 18

Answer 18

In vascular layer and connected to lens by ligaments

made of smooth muscle

Question 19

Iris

Answer 19

In vascular layer

Colored part regulating amount of light

Question 20

Pupil

Answer 20

In vascular layer
opening in the Iris
Black dot

Question 21

Lens

Answer 21

In vascular layer 
Behind pupil and iris
Transparent when healthy
Controls shape of eye as it focuses
Cataracts=milky colored=unhealthy 
Shape changed by accommodation
Separate eye into anterior/posterior

Question 22

Vitreous humor

Answer 24

Gel fluid in posterior cavity and is not recycled through bloodstream

Question 25

Retina

Answer 25

Part of nervous layer
lines the posterior wall
Detects light and transports impulses to the optic nerve
Made of photoreceptor cells (nearest choroid) and bipolar neurons and ganglion cells(inner layer)

Question 26

Photoreceptors

Answer 26

In retina
Respond to light
Rods cells (sense light)
Cone cells (sense color but need more light)

Question 27

Bipolar neurons

Answer 27

In retina

Transmit signal to inner layer made of ganglion cells

Question 28

Ganglion cells

Answer 28

Have large axons forming the optic nerve

Myopia

Answer 33

Eye is too long
image focused in front of the retina distant objects blurred nearsightedness
fixed with a concave lens

Question 34

Hyperopia

Answer 34

Farsightedness
image focused behind retina
eye too short
fixed with convex lens
