Answers with Verified Solutions | Latest
Updated 2026
Who discovered the traveling Georg von Bekesy
wave
(basilar membrane motion in
response to pressure)?
The __ view means energy for Passive (traditional)
basilar
membrane movement is provided
SOLELY by INCOMING SOUNDS
The __ view means basilar Active (current)
membrane
vibration is ENHANCED by
internal
processes that require
ADDITIONAL
ENERGY
The energy from incoming sound Insufficient
alone is __ because the basilar
membrane is immersed in fluid,
resulting in significant resistance
against its vibration
, What are the 3 types of evidence 1. Cellular
for 2. Tissue
the active process of the cochlea? 3. Functional
Evidence for active process at the 1. OHC motility (active shape changes)
CELLULAR level includes 2 2. Prestin motor protein in OHC
things:
What is evidence for active Non-linearity of basilar membrane
process movement
at the tissue level?
What are 2 pieces of 1. OAE
FUNCTIONAL 2. Dependence of OAE on OXYGEN
evidence for active process of SUPPLY (aka
cochlea? energy)
The outer hair cell __ when Shortens
depolarized by injection of electric
current from electrode
Where does depolarization occur Ion channels at the tip links of stereocilia
in
OHC?
What is OHC response to Motility
depolarization?
what is IHC response to Release neurotransmitters
depolarization?
