Transduction Pathway Flashcards
What happens first in the pathway?
Sound waves hit the pinna
What happens when the sound waves hit the pinna?
Sound waves then strike the tympanic membrane AKA eardrum
What happens after the sound waves strike the tympanic membrane?
Vibrations are then sent to the 3 tiniest bones in the body AKA anvil, hammer, and stirrup
What are the anvil, hammer, and stirrup collectively called?
Ossicles
What happens after the vibrations are then sent to the 3 tiniest bones in the body?
Vibrations are then passed to the cochlea
What is the cochlea lined w/?
Basilar membrane
What is within the basilar membrane?
Microscopic hairs
What does the basilar membrane hairs convert?
Sound waves into neural impulses
What happens at the end of the transduction pathway?
Neural impulses exit the ear at the auditory nerve and goes to the thalamus, temporal lobes, and auditory cortex
What is the analogy b/w the retina and cochlea?
The cochlea is to hearing as vision is to the retina
Which parts of the ear deal w/ sound waves?
Pinna and tympanic membrane
Which parts of the ear deal w/ vibrations?
Anvil, hammer, and stirrup AKA ossicles along w/ cochlea
Where do the sound waves turn into neural impulses?
Basilar membrane
What are the components of the ossicles?
Anvil, hammer, and stirrup
What is the tympanic membrane also known as?
Eardrum
