Crist

Crist (Old English for Christ), is the title given to a triad of Old English religious poems in the Exeter Book comprising a total of 1664 lines and dealing with Christ's Advent, Ascension and Last Judgment. It was originally thought to be one piece completed by a single author, but the poem is now broken up into three parts:

It and Beowulf are the primary examples of Anglo-Saxon literature.

Crista

A crista (/ˈkrɪstə/; plural cristae) is a fold in the inner membrane of a mitochondrion. The name is from the Latin for crest or plume, and it gives the inner membrane its characteristic wrinkled shape, providing a large amount of surface area for chemical reactions to occur on. This aids aerobic cellular respiration, because the mitochondrion requires oxygen. Cristae are studded with proteins, including ATP synthase and a variety of cytochromes.

With the discovery of the dual-membrane nature of mitochondria, the pioneers of mitochondrial ultrastructural research proposed different models for the organization of the mitochondrial inner membrane. Three models proposed were:

Baffle model – According to Palade, the mitochondrial inner membrane is convoluted in a baffle-like manner with broad openings towards the intra-cristal space. This model entered most textbooks and was widely believed for a long time.

Septa model – Sjöstrand suggested that sheets of inner membrane are spanned like septa (plural of septum) through the matrix, separating it into several distinct compartments.
