Question | Answer |
70% of sensory receptors are located in | the eye |
the eye is composed of what 3 layers? | fibrous, vascular(uvea) & inner layer (retina) |
our dominant special sense is: | vision |
what covers the iris & pupil? | cornea |
there is no blood supply in this eye structure. | cornea |
choroid region | supplies blood to all layers of eyeball |
ciliary body | ring of tissue surrounding lens |
ciliary muscles control: | len shape |
capillaries of ciliary____ | secretes fluid |
the suspensory ligament: | holds len in position |
what determines how much light enters the eye? | iris |
the colored part of the eye, composed of 2 layers is called the: | iris |
spincter pupillae | pupil size decreases - parasynmpahetic |
dilator pupillae | pupil size increases - sympathetic |
the pupil: | allows light to enter eye |
changes in pupil reflect our: | interests & emotional reactions |
bipolar cells are found in these 2 places: | nose & retinas |
primary visual cortex also goes by: | striate cortex |

center of vision | maculae lutea |
the macula lutea contains mostly: | cones |
what causes central vision blindness? | macular degeneration |
the 2 photorecptors are: | rods & cones |
