Outer Ear
This is the portion of the ear that connects the pinna to the tympanic membrane and middle ear cavity
What is the external auditory meatus?
This is one of the two tissue-covered openings found on the cochlea that is between the scala tympani and middle ear but not connected to the middle ear.
What is round window?
A fluid-filled space within the temporal bones that is snail-shaped spiral canal
What is cochlea?
The resultant pressure wave formed by areas of alternating condensation/compression and rarefaction changing at a steady rate
What is pure tone?
This is located in the inferior frontal gyrus where motor production of language is located and processing of sentence structure, grammar, and syntax is located.
this is the part of the ear that includes the pinna/auricle and the external auditory meatus/ear canal, that collects sound and directs sound to the middle ear
What is the outer ear?
This is part of the middle ear anatomy that connects the middle ear space to the back of the throat
What is Eustachian tube?
What is inner hair cells?
Measuring scale with a true zero point, each increment on the scale is equal to every other increment, and you can sum incremental units by addition
What is linear scale?
A hearing loss that is a combination of a conductive component plus a sensorineural component
this is the visible part of the ear that is shaped like a funnel to collect and send sound waves through the ear canal
What is pinna?
These are the three connected bones in the middle ear that form a chain
What is ossicular chain?
One of the two tissue-covered openings found on the cochlea, which is covered by the stapes footplate
What is oval window?
A ratio between the measured sound pressure and relative sound pressure, using logarithms. This is a usable unit of measurement for intensity of the range of human hearing
What is decibel (dB)?
The area of the brain in the lower temporal lobe responsible for speech perception
What is Wernicke's area?
The type of hearing loss caused by an abnormality in the external or middle ear characterized by the reduction in the conduction of sound in to the ear
What is conductive hearing loss?
This is the muscle of the middle ear that contracts bilaterally in response to high-intensity sounds to stiffen the ossicular chain, which protects the inner ear from intense sounds. This contraction results in attenuation of sound pressure reaching the inner ear
What is stapedius muscle?
Sensory end organs of balance within the vestibular labyrinth
What is semicircular canals?
A graphic representation of the disturbance of a medium in a sound wave, measured by units of length and depicted by the Greek letter lamda
What is wavelength?
Hearing loss in the inner ear due to damage to the cochlea and/or retrocochlear pathway, resulting in alterations of perception of sound frequency and intensity. This hearing loss also results in a loss of speech clarity due to damage to the neural fibers located in the cochlea
What is sensorineural hearing loss?
The function of this part of the ear is to transmit sound from the pinna to the eardrum.
This is the middle bone of the ossicular chain that comprises two processes: the short crus, which fits into a recess wall of the tympanic membrane, and the long crus, which is attached to the head of the stapes
What is incus?
This connects the two end organs of hearing and balance, the cochlea and semicircular canals, and houses the utricle and saccule
This decibel reference level is used to audiometrically measure an individual’s hearing level, and its reference varies with frequency according to minimal audibility curve
What is decibel hearing level (dB HL)?
The theory or concept of how sound waves travel and information is encoded through the cochlea
What is the traveling wave theory?
