Question

The middle ear converts A. air pressure waves to fluid pressure waves. B. air pressure waves to nerve impulses. C. fluid pressure waves to nerve impulses. D. pressure waves to hair cell movements.

Answer 1

Air stress waves undergo conversion to fluid pressure waves in the middle ear. Then conversion of fluid pressure into nerve impulses takes location in the inner ear. Thus, direct conversion of air stress waves to nerve impulses does now not appear however via fluid strain conversion.

When sound waves bend Stereocilia what happens?

Bending of greater stereocilia underneath the influence of a sound wave reasons mechanical opening of the mechanoelectrical transducer (MET) channels on the membranes of decrease stereocilia by way of tensioning the tip of every lower stereocilium with the facet wall of its associated greater one.

Which shape S is are worried in equalizing the pressure between the ear and the atmosphere?
