| What does the ciliary muscles do? | Adjust the shape of the eye and lens to focus on near or far objects |
| eye's image processor | retina |
| what does visual stimuli get turned into? | electric signals |
| Where does the processed image information get sent to and by what? | by electric signals along the optic nerve |
| vitreous liquid is also called what | vitreous humor |

| How does the ear collect sound? | they collect sound, turn the energy from the sound into movement, convert it again into electrical signals. Then they send the signals to brain where it gets sorted into meaning |
| ear root | aur/o, ot/o |
| sound, hearing root | acous/o, audi/o |
| suffix meaning hearing condition | -acusis |
| how many main divisions for the ear? | 3. outer, middle, inner |

| pinna | the fleshy part of the ear |
| where is the pinna located | sits on the mastoid bone of the skull |
| what does the pinna do and how | because of its funnel shape, it helps collect sound from the air and then send it down the ear canal toward the ear drum |

| salpinx function | drains the ear of any fluid and keeps the pressure inside the middle ear the SAME as outside the ear |
| what three bones are attached to the eardrum | incus, stapes, malleus (anvil, stirrup, and hammer) |
| what do the three tiny bones connected to the ear drum do | they move with the eardrum, transferring movement to the inner ear |
| ear wax root | cerumin/o |
| eustachian tube root | salping/o (means trumpet) |
| eardrum root | tympan/o, myring/o |
| mastoid process root | mastoid/o |
| cochlea | a shell-shaped organ in your inner ear filled with fluid and hair |
| inner ear alternate name | labyrinth |
| how does the fluid in the cochlea move | when the stapes moves, it then presses on the cochlea causing fluid to move |
| what system is the hair in your ears connected to | the nervous system |
| what are electrical signals carried by | the acoustic nerve |
| what is the critical job of the inner ear | maintaining balance |
| what sends information to the brain about the tilt, rotation, and motion of the head | vestibular system |
| how are hairs in the vestibular system canals moved | by movement and head angle |
| labyrinth root | labyrinth/o |
| vestibule root | vestibul/o |
| cochlea root | cochle/o |
