The knuckles
are the joints of the fingers and toes, which are brought into prominence when the hand is clenched and a fist is made. The word is derived from the diminutive of a word for bone, found in German Knochen/Knöchlein. Medically, it is said that the knuckles are formed by the metacarpophalangeal and interphalangeal joints of the finger. The knuckles at the base of the fingers are known as the major knuckles while the knuckles at the midfinger are known as the minor knuckles.
The sound you hear when you crack your knuckles is actually the sound of carbon dioxide gas bubbles bursting.
