What is the Shape of a Hand?

Published in Anatomy 1 min read

The shape of a hand can be described as a combination of simple geometric forms.

Understanding the Hand's Structure

Here's a breakdown of the hand's shape:

  • Palm: The palm has a general shape of a square, serving as the base for the fingers and thumb.
  • Fingers: Extending from one side of the palm, the fingers are best described as cylinders or rectangles.
    • Each finger is anchored by a knuckle, which can be visualized as an oval shape.
  • Thumb: The thumb emerges from the opposite corner of the palm.
    • It is supported by a triangular wedge of flesh, allowing for a wide range of motion.
