Types of Hand Bones
Types of Hand Bones provide the body with support and flexibility to manipulate objects in many different ways. Each hand contains 27 distinct bones that give the hand an incredible range and precision of motion.
The eight bones of the wrist are:
- Scaphoid: This bone is on the thumb side of the hand near the radius.
- Lunate: This bone rests between the scaphoid and triquetrum in the proximal row.
- Triquetrum: This small bone is on the pinkie side of the hand.
- Pisiform: This small bone is on the palm side of the triquetrum.
- Trapezium: This bone rests between the scaphoid and the metacarpal of the thumb.
- Trapezoid: The smallest bone in the distal row, this sits between the trapezium and the capitate.
- Capitate: The largest of the wrist bones, this sits between the trapezoid and the hamate behind the middle and ring fingers.
- Hamate: This small bone has a hook on the palm side. It rests next to the capitate on the pinkie side of the wrist.
