The Ear
- External ear-
includes the
pinna;
structure of
flesh and
cartilage
- Tympanic membrane-
eardrum is in the
middle ear and
vibrates at the same
frequency as the sound
wave that strikes it
- Frequency-
number of
compressions per
second. Measured
in Hz. Smaller
gaps between
waves=higher
frequency
- Amplitude- the
intensity. High
waves=higher intensity
- Frequency-
number of
compressions per
second. Measured
in Hz. Smaller
gaps between
waves=higher
frequency
- Ossicles/oval window-
connected to the tympanic
membran are three tiny
bones that transmit the
vibrations from the
ossicles to the oval
window (a membrane of
the inner ear
- Malleus/
hammer
- Incus/
anvil
- Stapes/
stirrup
- Malleus/
hammer
- Cochlea- snail
shaped structure in
the inner ear that has
three long, filled with
fluid, tunnels.
- Scala vestibular,
scala media,
scala tympani
- Scala vestibular,
scala media,
scala tympani
- Hair cells-
auditory receptors
that lie between
the basilar
membrane of the
cochlea on one
side and the
tectorial
membrane on the
other.
- Vibrations of the
fluid of the cochlea
displace the hair
cells which opens
the ion channels.
Depolarization
occurs as positive
charged potassium
wants to enter the
negatively charged
cell.
