Two new studies offer insights into the evolution and development of external ears, which appear in humans and other mammals ...

These observations suggest that the movement of stereocilia and the resulting modulation of their ionic currents is likely to be greater for outer hair cells than for inner hair cells. Several studies ...

The genes that build the cartilage of fish gills were repurposed to build the cartilage in mammals’ outer ears ...

The inner ear is divided into two fluid filled chambers - one inside the other. Figure 3 illustrates the basic organization of both the organs of hearing and balance. The fluid in the two chambers ...
