Eye Flashcards
What is the Superior Rectus?
Small muscles that swivel the eye to look up.
What are the Suspensory ligaments?
Hold lens with rings of cilliary muscles.
What is the Posterior Chamber?
Fluid filled cavity behind the iris.
What is the Iris?
Ring of muscle that changes size of pupil to regulate the amount of light entering the eye.
What is the Anterior Chamber?
Between cornea and iris, filled with aqueous humor fluid secreted by cilliary epithelium.
What is the Pupil?
Hole in iris that becomes wider in dim light.
What is the Scleral Venous Sinus?
A canal that aqueous humor fluid drains into.
What is the cornea?
The transparent layer covering the eye.
What is the Capsule of Lens?
A membrane enclosing the lens.
What is the Cilliary body?
Secreted aqueous humor fluid.
What is the lens?
Focused light onto the retina.
What is the Sclera?
A fibrous outer layer of eyeball.
What is the Choroid?
Lines the Sclera and forms the cilliary body and iris. Supplies blood and oxygen to the retina.
What is the optic disk?
Where the optic nerve joins the retina.
What is the optic nerve?
The optic nerve transports information from rods and cones of the retina to the brain.
What is the Retina?
Contains photoreceptors that react to light.
What is the Fovea?
Shallow depression in the retina where light is most accurately focused.
What is the conjunctiva?
The mucous membrane covering the eyeball.
What is the Vitreous Body?
The largest chamber of the eye.
What are Zonular Fibres?
The Suspensory ligaments of the lens.
What are the function of the eye’s sphincter muscles?
To change the size of the pupil due to changes in amount of light.
