🗑
the____ is the clear, window-like structure at the front of the eye   cornea  
🗑
beneath the cornea layer are the structures of the vascular tunic, which includes the choroid, iris, and ciliary body.   (info)  
🗑
the____has a very good blood supply and contains pigment which assists the eye eliminating light rays which have already been seen by the eye.   choroid  
🗑
the____ is the colored portion at the front of the eye. the color of the iris is genetically programmed.   iris  
🗑
at the center of the iris is a hole, the____   pupil  
🗑
the iris can change the size of the pupil to control the amount of light entering the eye. this structure is controlled by the occulomotor nerve.   (info on pupil)  
🗑
the___lies posterior to the iris.   ciliary body  
🗑
tiny fibers extend from the ciliary body to the clear, flexible____, allowing the ciliary body to control focusing by adjusting the shape of the lens. ciliary body is also controlled by the lens   lens  
🗑
the innermost layer, the neural tunic, of the eyeball is composed of the___   retina  
🗑
are nerve receptors that detect light, are located in the retina. these photoreceptors come in two varieties, rods & cones,   photoreceptors  
🗑
is the area of the retina where you have no vision at all.   optic disc  
🗑
there are no photoreceptors in this area because this is the beginning of the___. this area is easy to identify because a large vascular network emerges from the center of this structure and then spreads out to supply the rest of the retina.   optic nerve  
🗑
the_____ is the area of the retina where you have the best vision and contains a huge component of cone-type photoreceptors. this is located directly opposite the pupil, just lateral to the optic disc. No blood vessels are found in this immediate region.   macula lutea  
🗑
in the condition known as macular degeneration, the photoreceptors are lost from the macula region.   (info on macula lutea)  
🗑
the space at the back of the eye between the lens and the retina is referred to as the_____   posterior cavity  
🗑
the (space) posterior cavity contains a gelatinous mass called the___   vitreous body  
🗑
the vitreous body helps hold the retina in place, since the retina is only secured at the optic disc.   (info on vitreous body)  
🗑
the vitreous body helps hold the retina in place, since the retina is only secured at the optic disc.   (info on vitreous body)  
🗑
the space at the front of the eye between the lens and the cornea is called the____.   aqueous humor.  
🗑
too much of this aqueous humor can cause a condition known as glaucoma.   (info on aqueous humor)  
🗑
the anterior cavity is further subdivided into the ____   anterior chamber & posterior chamber  
🗑
is between the cornea and the iris   anterior chamber  
🗑
is between the iris and lens   posterior chamber  
🗑
the ear can be divided into the regions:   external, middle, and internal  
🗑
the ______ is the part design to be directly exposed to the environment.   external ear  
🗑
the flexible, flesh-colored piece of cartilage called the ??? is the portion of the ear which is visible from the outside.   pinna  
🗑
at the end of the external auditory canal is the ??? which serves as the barrier between the external and middle ear regions. this flexible sheet of dense collagenous connective tissue vibrates when the sound waves come in contact with it.   tympanic membrane  
🗑
the____ connects to the middle ear to the throat region. this tube helps regulate the air pressures on the tympanic membrane. unfortunately, this also creates a passageway for organisms which cause infections to get into the middle ear.   eustachian tube  
🗑
the ___ is indirectly exposed to the environment   middle ear  
🗑
the____ connects to the middle ear to the throat region. this tube helps regulate the air pressures on the tympanic membrane. unfortunately, this also creates a passageway for organisms which cause infections to get into the middle ear.   eustachian tube  
🗑
also in the middle ear are three tiny bones, the____?   ear ossicles  
🗑
the 3 tiny bones that are also called ear ossicles is are? the ossicles help to conduct the sound waves to the structures of the inner ear.   malleus, incus, and stapes.  
🗑
the 3 tiny bones that are also called ear ossicles is are? the ossicles help to conduct the sound waves to the structures of the inner ear.   malleus, incus, and stapes.  
🗑
the ____ is isolated from the external environment and contains several sets of nerve receptors, each involved with a different special sense activity.   inner ear  
🗑

🗑
cochlea contains receptors for hearing known as the??   organs of corti  
🗑

🗑
this serves as the entrance to the cochlea, allowing sound waves to enter into the inner ear structures.   oval window  
🗑
this serves as the exit from the cochlea, dissipating sound waves that have already passed through organs of corti.   round window
