Biology · Cell Structure and Function

Mitochondria are a double-membranous structure with an outer membrane and an inner membrane.

Crista means ridge or curve, and looking at the structure of the inner membrane of mitochondria, it seems like a series of crests.

Cisterna, which may sound similar to Crista, actually has a completely different role than Crista.

Cisterna is a flattened, stacked pouch found in ERs and Golgi Apparatus responsible for carrying enzymes and cargo proteins.

Lamella is a term referring to a thin, flat membrane, but we know that the inner membrane of mitochondria isn’t thin or flat; instead, it has extensive foldings.

Bifida is a spinal disorder completely unrelated to mitochondrial structure.
