The Eye Flashcards
What does the fibrous aspect of the eye consist of
Sclera
Cornea
What is the sclera
Most fibrous
Attachment of extraocular muscles
White part
What’s is the cornea
Transparent light entering
What are the components of the vascukar layer of the eye
Choroid
Ciliary body
Iris
What si the choroid
Layer of connective tissue
Nourish layers of retina
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
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
What’s is the neural layer
Photoreceptors
Retina
What’s the pigmented layer
Under neural layer
Attached to choroid layer
Support neural layer
What’s the centre of the retina
Macula
Where si the lens situated
Between vitrous humour and the pupil
What alters the lens shape
Ciliary body
What are the two fluid filled chambers called
Anterior and posterior chambers
Where is the anterior chamber
Between cornea and iris
Where is the posterior chamber
Between the iris and the ciliary processes
What are the anterior and posterior chambers filled with
Aq humour
What does aq humor do
A clear plasma like fluid that nourishes and protects the eye
What is the arterial supply and drainage from
Supplied by Opthalmic artery from internal carotid artery
Drowned by sup and inf Opthalmic veins
What are the three parts associated with the eyeball
Fibrous
Vascular
Inner layers
