Question | Answer |
eyes & ears | part of the nervous system |
eye consists | inner eye (eyeball) & outer eye (facial structure & eye muscles surrounding the eye) |
inner eye (eyeball)consists | outer, middle, & inner layers |
outer layers consists | cornea & sclera |
cornea | transparent anterior portion, allows light into the eye & participates in the focusing of light onto the back of the eye |
sclera | white of the eye (tough protective covering for most of the eyeball) |
middle layer consists | uvea |
uvea (YOU-vee-ah) consists | choroid, ciliary body, & iris |
choroid (KOH-roid) | inner lining of the sclera & contains blood vessels to nourish the eye |
ciliary body (SIL-ee-ahr-e) | lies at the anterior edges of choroid body & consists of ciliary muscles & ciliary process |
ciliary muscles | adjust the shape of the lens for focusing |
ciliary process | produces a watery substance (aqueous humor -- bathes the anterior region of the eye) |
iris | circular, colored portion of the eye |
pupil (central opening in the iris) | regulates the amt of light that enters the eye |
inner layer consists | retina |
retina contain | cones & rods (which are the cells that transform light into nerve impulses) |
cones | responsible for central & bright light vision |
rods | responsible for peripheral & low-light vision |
optic disc/blind spots | has no rods or cones & doesn't produce a visual images |
lens | is not considered to be part of one of the layers of the eye |
suspensory ligaments | where lens is located (posterior to the iris) & is held in place by ligaments |
refraction | when light passes thru the lens, it bent...bending is called |
lens accommodation | lens-shape changing |
cataracts | common age-related eye condition |
lens have two cavities | anterior & posterior cavities |
anterior cavity | contains aqueous humor (produced by ciliary processes) |
posterior cavity | contains vitreous humor (clear, jelly-like material) |
vitreous humor | maintains the spherical shape of the eyeball, holds retina firmly against the choroid and transmits light |
