|
What is audition?
|
The sense of hearing.
|
|
|
What is pitch?
|
The highness or lowness of a sound that corresponds to the frequency of the sound wave.
|
|
|
What is the eardrum?
|
A sheet of connective tissue separating the outer ear from the middle ear that vibrates in response to auditory stimuli and transmits sound waves to the middle ear
|
|
|
What is the ossicles?
|
Three tiny bones in the middle ear that vibrate in response to vibrations of the eardrum
|
|
|
What is the oval window?
|
The membrane-covered opening that separates the middle ear from the inner ear.
|
|
|
What is the cochlea?
|
The snail shaped organ in the inner ear that contains sensory receptors for hearing.
|
|
|
What is the basilar membrane?
|
The membrane in the cochlea that is attached to the organ of Corti.
|
|
|
What are the organs of corti?
|
A gelatinous structure in the cochlea containing the hair cells that serve as auditory receptors.
|
|
|
What are hair cells?
|
The auditory receptors that transform vibrations caused by sound waves into neural impulses that are then transmitted to the brain via the auditory nerve.
|
|
|
What is the auditory nerve?
|
The nerve that carries neural impulses from the ear to the brain, which gives use to the experience of hearing.
|
|
|
What is the place theory?
|
Pitch depends on the place along the basilar membrane that vibrates the most in response to a particular auditory stimulus.
|
|
|
What is the place theory?
|
Pitch depends on the place along the basilar membrane that vibrates the most in response to a particular auditory stimulus.
|
|
|
What is the frequency theory?
|
Pitch depends on the frequency of vibration of the basilar membrane and the volley of neural impulses transmitted to the brain via the auditory nerve.
|
|
|
What is the volley principle?
|
Relates the experience of pitch to the alternating firing of groups of neurons along the basilar membrane.
|
|
|
What is conduction deafness?
|
A form of deafness usually involving damage to the middle ear, in which there is a loss of conduction of sound vibrations through the ear.
|
|
|
What is nerve deafness?
|
Deafness associated with nerve damage usually involving damage to the hair cells or the auditory nerve itself.
