Anatomy and Functional Structure of the Ear Flashcards
1
Q
Outer Ear
A
abosorbs sound waves
2
Q
Middle Ear
A
conducts and amplifies sound waves
3
Q
Inner Ear
A
transduces sound waves and transmits neural impulses
4
Q
Pinna
A
absorbs sound waves and funnels them into the auditory canal
5
Q
Auditory canal
A
tunnel that sound waves travel through to pass through the middle ear
6
Q
Tympanic Membrane
A
- eardrum
- multiple layers of elastic tissue that encloes the auditory canal
- vibrates when sound waves pass through it
- heals well
- loses tension when in a loud enviorment
7
Q
Ossicles Bones
A
- Malleus
- Incus
- Stapes
- amplify sound waves by actining as procusion instruments
- directs sound waves to enterence of cochlea
8
Q
Malleus
A
- hammer
9
Q
Incus
A
Anvil
10
Q
Stapes
A
Stirrup
11
Q
Cochlea
A
transduces sound waves into neural implulses
12
Q
Basilar Membrane
A
- transduces sound waves using cochlear fluid and cochlear nerve hairs
- part of cochlea
13
Q
Auditory Nerve
A
- Acoustic Nerve
- transmits the neural impulses from the cochlea into the reticular activating system
14
Q
Eustachian Tube
A
- drainage tube
- releases air pressure and fluids from the throat
