More surface area for more neurons.
Do you mean crenulated, if so it is a margin with finely notched or rounded projections as on certain leaves. If you mean crenelated, that is a parapet or molding, as on the battlements of a castle.
The inner lining of the intestine has folds in it so as to increase the surface are. This greater aids in the absorption of nutrients from the gut. The larger the surface area, the greater the rate of absorption.
Gyri
No, because there is no such thing as the celestial sphere. So there is no inner surface of a celestial sphere.
To vibrate air into the inner ear so that the sound waves can eventually be interpruted (lots to it) by your brain
It all begins in the inner ear. In the inner ear, contains fluid. The fluid is also responsible for your balance.This tells your brain about the direction you're moving in. Now for example, say that you are reading a book in a moving car. Your inner ear is telling the brain that you're moving. But your eyes are on the book, so they tell the brain that you're not moving. The two information doesn't fit together, so this is what is causing car sickness in most people.
The inner membrane of mitochondria is ruffled becase it's to provide greater surface area. The inner membrane of the mitochondria is called cristae.
So your brain can hold more memory and processing space via an increase in [contained] surface area.
I think you are referring to the cristae. These are the folded parts of the inner membrane. The purpose is to increase surface area of the inner membrane against the matrix. The membrane is the site of the energy transfer in the mitochondria, so having more surface area is a plus.
The actual reason is that your eyes are telling your brain that you are moving, but the inner ears are telling your brain that you are sitting still. The brain cannot make sense of these opposing inputs, so it makes you dizzy and prone to vomiting.
The folded inner membrane of the mitochondria greatly increases the surface area of the membrane so that carbohydrates (simple sugars) can combine with oxygen to produce ATP.
This greatly increases the surface area of the membrane so that carbohydrates (simple sugars) can combine with oxygen to produce ATP.
