Anatomy Exam 3
| Term | Definition |
|---|---|
| The vitreous body | helps stabilize the eye and give physical support to the retina |
| The lens focuses light on the photoreceptor cells by | changing shape |
| There are three different types of cones, each one sensitive to a different color wavelength of light. These cones are designated | red, blue, and green |
| An area of the retina that contains only cones and is the site of sharpest vision is the | fovea |
| A blind spot in the retina occurs where | the optic nerve attaches to the retina |
| Sound waves are converted into mechanical movements by the | tympanic membrane |
| A structure that allows the middle ear to communicate with the nasopharynx is the | auditory tube |
| The basic receptors in the inner ear are the | hair cells |
| The structure that overlies the organ of Corti is the | tectorial membrane |
| The structure that separates the cochlear duct from the tympanic duct is the | basilar membrane |
| What we perceive as the pitch of a sound is our sensory response to its | frequency |
| The frequency of a sound is indicated to the nervous system by the | region of the organ of Corti that is stimulated |
| When viewing an object close to you, your lens should be more | rounded |
| Damage to the fovea of the eye would interfere with the ability to | see color |
| The sense of hearing is provided by receptors of the | inner ear |
| Night blindness can be treated by administering | vitamin A |
| The central opening in the eye through which light passes is the | pupil |
| The ciliary muscle helps to | control the shape of the lens |
| The pigmented portion of the eye is the | iris |
