The Fluid Filled Cochlea. The pressure changes in the cochlea caused by sound entering the ear travel down the fluid filled tympanic and vestibular canals which are filled with a fluid called perilymph.
Those who love the size of the original iPad Mini 1 will be pleased to find that the size remains unchanged. Both the iPad Mini 1 and the iPad Mini 2 both measure in with a height of 7.87 inches and a width of 5.3 inches. The iPad Mini has only a slight difference in depth, while it weighs slightly more. However, it is still lightweight enough for anyone who wants a small and portable tablet.
The first generation iPad Mini features partially the same hardware as the iPad 2. Both screens have resolutions of 1024x768, but the iPad Mini has a smaller screen and thus higher pixel density than iPad 2 (163 PPI vs. 132 PPI). Unlike the iPad 2, it has 5 MP and 1.2 MP cameras and the Lightning connector.
