ASL FINAL NOTES

What is number 9?

Nerves (These carry electro-chemical signals from the inner ear to the brain.)

Noun-Verb pairs in ASL usually mean that both may have the same handshape, but differ with their movement. Nouns are usually signed once or directionally, and verbs are usually signed twice.

False

What insturment is used to look into the ear?

Otoscope

What is number 1?

Pinna (The external part of the ear that collects sound waves.)

What is number 10?

Semicircular Canals (Three loops of fluid-filled tubes that are attached to the cochlea in the inner ear; they help us maintain our sense of balance.)

What is number 6?

Stirrup (A tiny, U-shaped bone that passes vibrations from the hammer to the stirrup.)

A cochlear implant is very different from a hearing aid. Hearing aids amplify sounds so they may be detected by damaged ears. Cochlear implants bypass damaged portions of the ear and directly stimulate the auditory nerve.

True

As of today, Gallaudet University still is the world's only liberal arts university where all programs and services are specifically designed for Deaf and Hard of Hearing students.

True

Noise-Induced Hearing Loss can occur anytie a sound is higher than how many decibels?

85dB

What is otosclerosis?

A disease that causes bony growth on the ossicles and causes the stirrup to become immobile, thus not allowing sound to be transferred to the cochlea.

What is Meniere's Disease?

A problem involving fluid pressure in the cochlea. Causes, dizziness, hearing loss, and tinnitus.

What is number 5?

Anvil (A tiny bone that passes vibrations from the hammer to the stirrup.)

what is the doctor who tests hearing called?

Audiologist

Which is the instrument used to test your hearing?

Audiometer

What is number 8?

Cochlea (A spiral-shaped, fluid-filled, inner ear structure; it is lined with cilia that move when vibrated and cause a nerve impulse to form.)

Sound is measured in what unit?

Decibels

What is number 2?

Ear Canal (The tube through which sound travels to the ear drum.)

What is number 3?

Ear Drum (A thin membrane that vibrates when sound waves reach it.)

What is number 7?

Eustachian Tube (A tube that connects the middle ear and the air outside.)

The correct way to sign the color of ivory/cream is to:

sign WHITE and frown/eye squinted along with normal sign movement.

What is number 4?

Hammer (A tiny bone that passes vibrations from the eardrum to the anvil.)

What is presbycusis?

Hearing loss caused by natural aging.

What is Tinnitus

Hearing sound when no sound is present.

Some of the higher education institutions that serve a large number of Deaf and Hard of Hearing students are . . .

Lamar University, McDaniel College, NTID, and Gallaudet University.
