What’s Anatomy of the Hand?
The human hand is a complex structure consisting of 27 bones, including the carpals (wrist bones), metacarpals (bones of the hand), and phalanges (finger bones). It features a diverse range of muscles, tendons, and ligaments that facilitate intricate movements and grip. The hand is divided into three main parts: the proximal region (near the wrist), the middle part (palm), and the distal portion (fingers). Each finger comprises three phalanges, except for the thumb, which has two. The hand’s unique anatomy allows for fine motor skills, enabled by the opposable thumb, which provides a range of functionalities essential for daily tasks and tool use. Additionally, numerous nerves and blood vessels supply the hand, making it sensitive and functional.
