Elevated the eye and turns it medially
Superior rectus
What are the extrinsic eye muscles?
Superior rectus, inferior rectus, superior oblique, lateral rectus, medial rectus, and inferior oblique
Depressed eye and turns it medially
Inferior rectus
Depresses eye and turns it laterally
Superior oblique
Moves eye laterally
Lateral rectus
Moves eye medially
Medial rectus
Elevated eye and turns it laterally
Inferior oblique
Fluid that provides nutrients to the lens and cornea
Aqueous humor
The white if the eye
Sclera
Area that lacks photoreceptors
Optic disk
Controls the shape of the lens
Iris
Nutritive layer of the eye(contains blood vessels)
Choroid coat
Later containing rods and cones
Retina
Anterior most part of the eye
Cornea
Area with the clearest vision
Fovea
What are the smooth muscles(intrinsic eye muscles)
Ciliary body
Iris
What are the refractory media of the eye
Cornea, iris, lens, vitreous humor
When you look at something far away the ciliary muscle is
Relaxed
When you look at something close the ciliary muscle is
Contracted
When you look at something far away the lens is
Less convex
When you look at something close the lens is
More convex
When you look at something far away less light is
Refracted
When you look at something close more light is
Refracted
Light bending
Refraction
Ability to focus for close vision
Accommodation
Normal vision
Emmetropia
Farsightedness
Hyperopia
Reflex-construction of pupils when they are exposed to bright light
Photo pupillary reflex
Clouding of the lens
Cataract
Nersightedness
Myopia
Blurred vision form unequal curvatures of the lens or cornea
Astigmatism
Increased pressure inside the eye
Glaucoma
Medial movement of the eyes during focusing on close objects
Convergence
Reflex construction of the pupils when viewing close objects
Accommodation pupillary reflex
Inability to see well in the dark
Night blindness
Is the eye concave or convex?
Convex
Farsightedness light is focused?
Behind the retina
Farsightedness is treated with what kind of lens
Convex
Nearsightedness light is focused
In front of the retina
Nearsightedness is treated with what kind of lens
Concave
Help give you color vision
Comes
Help you see in dim light
Rods
What are the bones of the ear?
Stirrup, anvil, and hammer
What does the hammer do?
Moves with the ear and transfers the vibration to the anvil
What does the anvil do?
It passes the vibration I the stirrup
What does the stirrup do?
It receives the vibration and pressed on the oval window of the inner ear
