what is the choroid
supplies blood to the outer layers of the retina, it fils back of retina
what is the iris
contraol the diameter of the pupil

vitreous humour
what sepeartes he antieor and postior segments of the eye
lens
what is the cilary body connected to
cilary and lens
what is the difference in the viscosity of aqueous and virteous humour
aqueous humor more watery
vitreous humour is more gel like ,
what is the location of hte anteiror and posterior chamber of the anterior segment of the eye

postoer , hennign iris but infot of lens
trabecualr meshowrok fucntion
spongy tissue that drain eye of aqueous humour
schlemss canal
moves fluid from eye to the systemeic circulation

tarsal plate
meibomian glands
conjunctiva
role of ocnjuctiva
thin vascular layer that covvers inner surface of the eyelids and loops back over sclara
where is the lacrimal gland located
over latearl superior part of eye orbit
what ithe innervationfo the lacrimal appartus
parasympatheic through facial nerve
where do the tears drain for the lacrimal appartus
lacrimal sac
what bone doe the lacriaml sac sit over
lacrimal bone
which meatus of the nasl cavity does the lacrimal apparatus drain into

roof of orbit
upper eyelid
what is the origin of the superoir oblique and infeir oblique mucles
superior oblique - lesser wing of sphenoid
inferior obioble- meidla part of obit floor
what is teh nerve that supplies superior oblique
trochlear nerve
what is the nerve that suppleis lateral revtus
abducent (6)
what nerves supply all hte eye stucres apart form lr and so

what do the long posteior cilary aters supply
antiero choild and cilary body and iris
which veins drain into the cavernous sinus
superior and inferio opthalmic viens
wher eis the caverous sinus
immedaly postieor to teh orbit
what passes though cavernous sinsu
