What Conversion of Sensory Input Occurs in the Mammalian Middle

Question

What conversion of sensory input occurs in the mammalian middle ear?
A) air pressure waves to fluid pressure waves
B) fluid pressure waves to air pressure waves
C) air pressure waves to nerve impulses
D) fluid pressure waves to nerve impulses

Accepted Answer

The mammalian middle ear converts air pressure waves into fluid pressure waves. This occurs as sound waves travel through the air and are then transmitted through the eardrum and ossicles (tiny bones in the middle ear) into the cochlea, where they are converted into fluid pressure waves.
