Sclera
Cornea

2

What is the sclera

Most fibrous
Attachment of extraocular muscles
White part

3

What's is the cornea

Transparent light entering

4

What are the components of the vascukar layer of the eye

Choroid
Ciliary body
Iris

5

What si the choroid

Layer of connective tissue
Nourish layers of retina

6

What are the two parts of the ciliary bodya Nd what do they do

Ciliary muscles - smooth muscle fibres attach to ciliary processes
Ciliary body - controls the shape of the lens and forms the aq humour

7

What si the iris

Has the pupil centrally
Diameter altered by smooth muscles (autonomic)
Between lens and cornea

What is the internal layer of the eye

Retinal layer which has two parts
Neural and pigmented

9

What's is the neural layer

Photoreceptors
Retina

10

What's the pigmented layer

Under neural layer
Attached to choroid layer
Support neural layer

11

What's the centre of the retina

Macula

12

Where si the lens situated

Between vitrous humour and the pupil

13

What alters the lens shape

Ciliary body

14

What are the two fluid filled chambers called

Anterior and posterior chambers

15

Where is the anterior chamber

Between cornea and iris

16

Where is the posterior chamber

Between the iris and the ciliary processes

17

What are the anterior and posterior chambers filled with

Aq humour

18

What does aq humor do

A clear plasma like fluid that nourishes and protects the eye

19

What is the arterial supply and drainage from

Supplied by Opthalmic artery from internal carotid artery
