The knuckles are the joints of the fingers. The word is cognate to similar words in other Germanic languages, such as the Dutch "knokkel" (knuckle) or German "Knöchel" (ankle), i.e., Knöchlein , the diminutive of the German word for bone ( Knochen ).
This term is translated literally as "foot-lock". In fact, although the term fetlock does not specifically apply to other species' metacarpophalangeal joints (for instance, humans), the "second" or "mid-finger" knuckle of the human hand does anatomically correspond to the fetlock on larger quadrupeds.
In human anatomy, the metacarpal bones or metacarpus, also known as the "palm bones", are the appendicular bones that form the intermediate part of the hand between the phalanges and the carpal bones (wrist bones), which articulate with the forearm.
Hearing “snap, crackle, pop!” with no visible sign of the Rice Krispie trio can only mean one thing: snapping joints—likely knuckle cracking, to be more specific.Whether or not the sensation ...
Researchers said on Wednesday they have settled the issue of what occurs inside knuckles to trigger the familiar popping sound. Snap, crackle, pop: study reveals secret behind knuckle-cracking ...
The radial nerve innervates the finger extensors and the thumb abductor; that is, the muscles that extend at the wrist and metacarpophalangeal joints (knuckles) and abduct and extend the thumb. The median nerve innervates the flexors of the wrist and digits, the abductors and opponens of the thumb, the first and second lumbricals. The ulnar ...
The cracking of joints, especially knuckles, was long believed to lead to arthritis and other joint problems. However, this is not supported by medical research. [2] [3] The cracking mechanism and the resulting sound is caused by dissolved gas (nitrogen gas) cavitation bubbles suddenly collapsing inside the joints. This happens when the joint ...
The chimpanzee primarily uses two modes of locomotion: knuckle-walking, a style of quadrupedalism in which the body weight is supported on the knuckles (or more properly on the middle phalanges of the fingers), and brachiation (swinging from branch to branch), a style of bipedalism in which flexed fingers are used to grasp branches above the ...
