No, that would be ribs.
The loin is from the lower part of the back between the ribs and the sirloin.
The loin are the sides between the lower ribs and pelvis, and the lower part of the back. It is often used when describing the anatomy of humans and quadrupeds (such as horses, pigs or cattle). The anatomical reference also carries over into the description of cuts of meat from some such animals, eg. tenderloin or sirloin steak.
