vibrate differently which makes it possible for us to distinguish the different sounds we
hear.
Outer hair cells (13) convert detected sound vibrations into electrical impulses and
conduct them to the vestibular nerve (14). Then the information from both ears meet in the
superior olivary complex (15). The organs involved in the auditory pathway are as follows:
Inferior colliculus (16), medial geniculate body (17), and finally the auditory cortex (18). 34
The blue line inside the brain shows the route for high pitches and the red for low
pitches. Both cochleas in our ears send signals to both hemispheres of the brain.
As is clear, the system enabling us to hear is comprised of different structures that
have been carefully designed in the minutest detail. This system could not have come into
existence "step by step", because the lack of the smallest detail would render the entire
system useless. It is, therefore, very obvious that the ear is another example of flawless
creation.
