What is a "knuckle"?
The knuckle is the bony joint where the finger connects to the hand. It is formed by the articulation of the metacarpal bone and the phalanges of the finger. The knuckles provide flexibility and dexterity, allowing for precise movements and gripping. They play a vital role in activities that involve hand manipulation and fine motor skills. The knuckles are also commonly used in hand-to-hand contact, such as in boxing or martial arts. Understanding the anatomy and function of the knuckles is important for hand coordination, tactile sensation, and overall hand strength.
