in foldings on the surface of the brain
The infoldings of the brain are the sulci, and the outward foldings are the gyri.
The infoldings of the inner membrane of the mitochondria are called cristae. These structures increase the surface area of the inner membrane, allowing for more space for chemical reactions involved in cellular respiration to take place.
touch the surface of the brain how does it feel
The convolutions in the brain increase surface area. In simpler words, those lines and ridges in the brain are what increases the surface area.
The regularly spaced infoldings of the sarcolemma are called T-tubules. They help facilitate the rapid transmission of action potentials into the interior of muscle fibers, allowing for synchronous muscle contraction.

transverse or T tubules
the synovial membrane becomes intensely inflamed. Usually thin and delicate, the synovium becomes thick and stiff, with numerous infoldings on its surface. The membrane becomes invaded by white blood cells
The folds in the brain increase the surface area. It nearly triples the surface area. As we grow, more of these bends form.
