Hearing and Balance Flashcards
Auditory Canal
Part of external ear that leads sound to the eardrum
Acoustic Nerve
Nerve that connects ear and brain
Fluid filled system, maintains equilibrium
Bony labyrinth
The part of the ear you can see, the main function of it is to catch sound waves and pass them further into the ear
Auricle
Another word for ear drum, boundary between external and middle ear
Tympanic Membrane
Cochlea
Shell shaped, last destination of sound waves
Another term for the inner ear
Labyrinth
Utricle and Saccule
Have hairs that detect the fluid in the vestibular apparatus
2 layers of the labyrinth
Bony labyrinth and membranous labyrinth
Equilibrium
Balance
Translates vibrations to action potentials
Organ of Corti
Labyrinth
Another term for the inner ear
Auricle
The part of the ear you can see, the main function of it is to catch sound waves and pass them further into the ear
Inside the bony labyrinth that follows its shape
Membranous Labyrinth
3 major areas of ear’s function
External and middle ear are only responsible for hearing while the inner ear is responsible for hearing and balance
Part of external ear that leads sound to the eardrum
Auditory Canal
Organ of Corti
Translates vibrations to action potentials
Membranous Labyrinth
Inside the bony labyrinth that follows its shape
Tympanic Membrane
Another word for ear drum, boundary between external and middle ear
These 2 part of the inner ear have hairs that detect the fluid in the vestibular apparatus
Utricle and Saccule
Tympanic Cavity
Another word of the middle ear
Bony labryinth
Fluid filled system, maintains equilibrium
3 major areas of the ear
External, middle, inner
Steps sound takes to be registered in the human brain
- The auricle guides the sound down into the ear
- The sound goes through the auditory canal
- The ear drum vibrates and the vibrations get passed down to
- 3 bones in the ear vibrate more, and it gets passed down to the tympanic cavity which leads the sound to
- into the inner ear into the cochlea which transfers the sound into action potential
Nerve that connects ear and brain
Acoustic Nerve
3 bones in the ear
Anvil, hammer, stapes
Anvil, hammer, stapes
3 bones in the ear
Another word of the middle ear
Tympanic Cavity
Shell shaped, last destination of sound waves
Cochlea
It has fluid inside of it that is controlled by movement of your head
Vestibular Apparatus
Vestibular Apparatus
It has fluid inside of it that is controlled by movement of your head
Balance
Equilibrium
