Description:
The flow direction of sound as a traveling wave is sketched in. The position of the organ of Corti as sound recipient is shown as well.
Furthermore it is clearly illustrated that the scala tympani and the scala vestibuli are one single fluid cavity.
Information and ideas:
This graphic helps to make clear that the whole cochlea is a fluid canal and that it is there where the vibrations of sensory hair cells are converted into nerve impulses.
Can be used on worksheets or as overhead transparency.
Relevant for teaching:
Structure and functions of a sense organ
Reception of stimuli and transmission of information
Functions of senses
