Front 16

What controls lens shape?

Back 16

Cilliary body

Front 17

What does the choroid do?

Back 17

Big black part that contains melanin. It absorbs the light so we are trying to see 6 different things.

Front 18

What are the functions of the Iris?

Back 18

Color part of the eye and controls the pupil size to control how much light comes in.

Front 19

What is the pupil?

Back 19

hole in the eye that lets light in. Dilate when in fight or flight response

Front 20

What are the areas in the sensory tunic?

Back 20

Pigmented layer, neural layer, fovea centralis, optic nerve

Front 21

What is the single cell think layer of the retina that absorbs light and prevents it from scattering?

Back 21

Pigmented layer

Front 22

What is the neural layer

Back 22

Contains the millions of photoreceptor cells that transduce light energy.

Where is the image projected?

Back 31

Retina

Front 32

What are the 2 types of humor?

Back 32

Aqueous and viteous

Front 33

What liquid is between the cornia and lens and what does it do?

Back 33

Aqueous humor - continuously trains and replenishes, nutrients and oxygen to the lens and cornea

Front 34

What liquid in in the posterior section of the eye and what does it do?

Back 34

Viteous humor - transmits light, holds retina to the rear of the eye and contributes to intraocular pressure and it is never replaced, maintains eye shape

Front 35

What is glaucoma?

Back 35

aqueous humor can no longer leave and pressure builds up between lens and cornea putting pressure on the back of the eye and destroys retina
