The knuckles are the joints of the fingers. The word is cognate to similar words in other Germanic languages the diminutive of the German word for bone (Knochen). Anatomically, it is said that the knuckles consist of the metacarpophalangea (MCP) and interphalangeal (IP) joints of the finger. The knuckles at the base of the fingers may be referred to as the 1st or major knuckles while the knuckles at the midfinger are known as the 2nd and 3rd, or minor, knuckles. However, the ordinal terms are used inconsistently, and can be found referring to any of the knuckles.
