eye anatomy

Question 1

layers of eyeball

Answer 1

fibrous layer
vascular layer
retina

Question 2

fibrous layer

Answer 2

consists of sclera and cornea which are continuous with eachother

function to provide shape to eye and support deeper structures

Question 3

sclera

Answer 3

majority fibrous layer
attachment for extraocular muscles

white part of eye

Question 4

cornea

Answer 4

transpartant

refracts light entering eye

Question 5

vascular layer

Answer 5

consists of choroid, ciliary body and the iris

Question 6

choroid

Answer 6

layer of connective tissue and blood vessels

provides nourishment to outer layers of retina

Question 7

ciliary body

Answer 7

ciliary muscle and ciliary processes

controls shape of lens
produces aqueous humour

Question 8

iris

Answer 8

circular structure with aperture in centre - pupil

between lens and cornea

Question 9

retina

Answer 9

composed of 2 layers

• pigmented layer
• neural layer

Question 10

retina - pigmented layer

Answer 10

attached to coroid

supports choroid absorb light

Question 11

retina - neural layer

Answer 11

photoreceptors - light detecting cells

Question 12

optic part of retina

Answer 12

posteriorly and laterally - where both layers of retina are present

Question 13

vitreous body

Answer 13

transparent cell which fills posterior segment of eyeball - area posterior to lens

Question 14

vitreous body - functions

Answer 14

contributes to magnifying power eye
supports lens
holds layers of retina in place

Question 15

lens

Answer 15

located anteriorly, between vitreous humour and pupil

shape is controlled by ciliary body, altering its refractive power

Question 16

anterior chamber

Answer 16

between cornea and iris

Question 17

posterior chamber

Answer 17

between iris and ciliary processes
