Front Back
Contains the radial muscle and Circular Muscles
Iris
Nerve that carries information from the photoreceptors to the primary visual cortex
Optic Nerve
Cranial Nerve II
Optic Nerve
Sensory Nerve For Vision
Optic Nerve
Muscle that raises the eyelid
Levator Palpebra Superioris
Location of the pimrary visual cortex
Occipital Lobe
Elevated intracranial pressure compresses this nerve to cause ptosis of the eyelid
Oculomotor Nerve
Muslce that move the eyeball in its socket
Extrinsic Eye Muscles
The Meaning of 4 in LR8SO4
Trochlear Nerve
The Meaning of 6 in LR6SO4
Abducens
The structures indicated by LR and SO in LR6SO4
Lateral Rectus and Superioir Oblique
Elevated intracranial pressure compresses this nerve to cause fixed and dialated pupils
Radial Muscle
Muscle that contracts and relaxes to change the shape of the lense
Ciliary Muscle
Contraction of this muscle widens the pupil
Radial Muscle
Contains the muscles that cause mydriasis and miosis
Circular Muscle
Includes the superior inferior medial and lateral rectus also includes the supererioir and inferior oblique.
Extinsic Eye Muscles
Muscles that allow you to look at the ceiling without moving your head
Extrinsic Eye Muscles
Anterioir extension of the sclera; this avascular structure allows light to enter the eye
Cornea
Outermost layer or Tunic of the eyeball
Sclera
Called the "window of the eye" because it is the first structure through which light enters the eye
Cornea
Colored portion of the eye
Iris
Middle tunic; has a rich supply of blood and nourishes the retina
Choroid
The shape of this structure changes in response to contraction and relaxation of the ciliary muscles; it refracts light waves
Lens
Venous sinus that drains aqueous humor
Canal of Schlemm
Contact lenses are placed on this surface
Lens
Layer that extends anterioirly to form the iliary body and the iris to form the ciliary body and the iris
Choroid
Innermost tunic; it is the nervous tissue that contains the photoreceptors
Retina
The Fluid that helps maintain the shape of the anterioir cavity
Aqueous Humor
Layer that contains the rods and cones
Retina
Circular opening in the center of the iris
Pupil
Blinde Spot
Optic Disc
Fluid that is formed by the ciliary body and drains through the canal of schlemm
Aqueous Humor
Ciliary muscles attach to these bands of connective tissue that pull on the lens
suspensory ligaments
mucous membrane that lines the inner surface of the eyelids and folds back to cover a part of the anterioir surface of the eeball
Conjunctiva
Layer that includse the macula lutea and fovea centralis
Retina
Gel Like substance that fills the posterior cavity
Vitrous Humor
Structure that secretes squeous humor and gives rise to intrinsic eye muscles called the ciliary muscles
Ciliary Body
Composed of muscles that determine the size of the pupil
Iris
Layer that sends information along the optic nerve to the occipital lobe
Retina
Gel Like fluid that gently pushes the retina against the choroid
vitreous humor
Layer that contains melanocytes to diminish glare as light enters the posterioir cavity
Choroid
