Eyes:

Question 1

Eyes:

Answer 1

visual sense organs within bony orbits of the skull

supplied by the OPTIC nerve

Question 2

Eye Outer layer:

Answer 2

CORNEA-controls an d focuses light into eyes

SCALERA: opaque membrane(white of eyes) protects/supports eyeballs

Question 3

Eye Middle layer:

Answer 3

CHOROID:thin layer of tissue that cotains blood vessels for oxygen/nutrients for eyes

melanin prvents light waves from reflecting back out of eyes

Question 4

Eye Innerlayer:

Answer 4

RETINA
IRIS
PUPIL

Question 5

Retina:

Answer 5

receive light that the eyes lens has focused

convert the light into neural signals

send these signals on to the brain for visual recognition.

Question 6

Iris:

Answer 6

controls the diameter of the pupil, reponsible for eye color (pigment cells)

Question 7

Pupil:

Answer 7

anterior opening, allows light in

Question 8

Eye lense:

Answer 8

hangs from the siallary muscle

to change the angle to RETRACT light

bends/refracts light & focuses light on retina

Question 9

Anterior chamber:

Answer 9

aquaious humor with watery fluid b/w the cornea & iris

Question 10

Posteior chamber:

Answer 10

vitrous humor b/w iris & eye lense

holds the retina against the choroid

Question 11

Rods:

Answer 11

to see during low-light conditions
peripheral vision
photoreceptor cells

Question 12

Cones:

Answer 12

visual acuity

viewing objects in sharp focus & color vision

Question 13

how do you see?

Answer 13

light contacts the retina

bipolar cells

reaches the rods/cones in the photo-receptor cell layer
