Auditory System
Receptors that detect sound waves and pressure on the skin and ear.
What is mechanreceptors
Pitch is the perceptual experience of this sound characteristic.
What is frequency
This is the most fundamental dimension of music.
What is pitch
This part of the ear is involved in both hearing and equilibrium?
What is the inner ear?
This part of the ear is the first to catch sound waves.
What is pinna/auricle?
Loudness is the perceptual correlate of this sound characteristic.
What is amplitude?
Someone who can very accurately produce sound notes without comparing it to other notes has this.
What is absolute pitch?
The middle ear/tympanic cavity has these three tiny bones. (which together are called)
Ossicles
This part of the ear vibrates in response to sound.
What is the eardrum/tympanic membrane
This area of the brain is responsible for processing sound
What is the primary auditory cortex?
The left hemisphere is more active during this.
What is language?
The ossicles do this to sound.
What is to amplify sound?
This structure regulates the flow of ions into the cell.
What is stereocilia?
This type of organization refers to neighboring neurons responding to neighboring sounds.
What is tonotopic
(in the cortex and in the cochlea,)
Music perception is lateralized in this hemisphere
What is the Right hemisphere
This is the snail-shaped structure of the inner ear that houses the sensory receptors that are responsible for sensory transduction.
What is the cochlea?
This is a structure on the basilar membrane composed of hair cells and dendrites of auditory nerve fibers.
What is The organ of Corti?
The base basilar membrane is thicker and stiffer and therefore more responsive to this?
What is high-frequency sounds?
This area was named after a neurologist and is responsible for speech production?
What is Broca's area?
Movement of the basilar membrane causes hair cells to bend which does this.
What is release neurotransmitters
This is the pathway sound takes to get to the brain. (Must state all 4 discussed in lecture)
superior olivary nucleus- inferior colliculus- medial geniculate nucleus (MGN) Thalamus- primary auditory cortex (or auditory receiving area, A1) in the temporal lobe of the cortex.
