Understanding the Human Hand: Anatomy, Function, and Common Injuries
The human hand is a remarkable structure, with 27 bones and over 30 muscles facilitating its movement. Essential for daily tasks and hobbies, hands play a vital role in our lives. However, they are susceptible to injuries like fractures and sprains, especially in accidents. Notably, one-fourth of all bones in the human body are located in the hands. As we age, our hands grow larger, and interestingly, popping knuckles releases nitrogen bubbles that create sound. Learn more about the anatomy and functions of the human hand.
