Description
As with all quadrupeds, the tenderloin refers to the psoas major muscle ventral to the transverse processes of the lumbar vertebrae, near the kidneys.
The tenderloin is an oblong shape spanning two primal cuts: the short loin (called the sirloin in Commonwealth countries) and the sirloin (called the rump in Commonwealth countries). The tenderloin sits beneath the ribs, next to the backbone. It has two ends: the butt and the "tail". The smaller, pointed end—the "tail"—starts a little past the ribs, growing in thickness until it ends in the "sirloin" primal cut, which is closer to the butt of the cow. This muscle does very little work, so it is the tenderest part of the beef.

Processing and preparation
Whole tenderloins are sold as either "unpeeled" (meaning the fat and silver skin remain), "peeled" (meaning that the fat is removed, but silver skin remains), or as PSMOs ("pismos"), which is short for "peeled, side muscle on" (side muscle refers to the "chain"). Since it is the most tender part of the animal, beef dishes requiring exceptionally tender meat, such as steak tartare, are ideally made from the tenderloin.
Cuts
The three main "cuts" of the tenderloin are the butt, the center cut, and the tail.
The butt end is usually suitable for carpaccio, as the eye can be quite large; cutting a whole tenderloin into steaks of equal weight will yield proportionally very thin steaks from the butt end.
The center cut is suitable for portion-controlled steaks, as the diameter of the eye remains relatively consistent. The center cut can yield filet mignon or tenderloin steak, as well as the Chateaubriand and Beef Wellington.
The tail, which is generally unsuitable for steaks due to size inconsistency, can be used for Tournedos, rounds too small to serve as an individual filet mignon-sized entre, typically plated as a pair and often cooked with bacon or lard for added richness, or used in recipes where small pieces of a tender cut are called for.
