Curved Membrane effect: Movements of the tympanic membrane are more at the periphery than at the centre where malleus is attached which provides some leverage. This is called as curved membrane effect.

I am unable to comprehend how movement is more at periphery than at centre. Practically movement is more at the centre as can be seen from this .gif or from following image: enter image description here

So, why it is said that movement is more at periphery?

  • $\begingroup$ "...as seen from the gif" Is the gif not accurate in showing the curved membrane effect? $\endgroup$
