The Fascinating Functional Anatomy of the Human Hand

Abstract

Aliberti Stefano

The human hand is an intricate and remarkable tool, enabling us to interact with the world in ways that no other species can match. Its complex structure, comprising bones, muscles, tendons and nerves, allows for a remarkable range of movements and dexterity. In this article, we will explore the functional anatomy of the human hand and appreciate the incredible biomechanics that underlie our ability to perform a wide variety of tasks. The skeletal framework of the hand consists of 27 individual bones divided into three main sections: the carpals (wrist bones), metacarpals (palm bones) and phalanges (finger bones). The wrist contains eight carpal bones, which form a flexible bridge between the forearm and the hand. These bones include the scaphoid, lunate, triquetrum, pisiform, trapezium, trapezoid, capitate and hamate.
