Your wrist is made up of eight small bones called the carpal bones, or the carpus. These irregularly shaped bones join your hand to the two long forearm bones: the radius and ulna.
Bones provide the main structural support in your hand and wrist. They give them their shape and are the anchors other pieces are connected to. There are 19 bones in each of your hands. They’re grouped together by their location and function: Metacarpals: The bones that are in your palm and give it its shape.
The carpal bones in the human wrist are arranged in two rows – the proximal carpal row, articulating with the lower arm bones radius and ulna, and the distal carpal row, articulating with the metacarpals.
The wrist connects the hand to the forearm. It consists of the distal ends of the radius and ulna bones, eight carpal bones, and the proximal ends of five metacarpal bones.
The wrist anatomy (joint) is made up of bones that form two surfaces: one is like a cup (formed by the end of the radius bone and a cartilage disk), and the other is like a ball (formed by the scaphoid, lunate, and triquetrum bones).
Bones and Joints. There are 15 bones that form connections from the end of the forearm to the hand. The wrist itself contains eight small bones, called carpal bones. These bones are grouped in two rows across the wrist. The proximal row is where the wrist creases when you bend it.
Explore the anatomy and function of the hand and wrist bones with Innerbody's interactive 3D model. The bones of the hand and wrist 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.
In the hand proper a total of 13 bones form part of the wrist: eight carpal bones — scaphoid, lunate, triquetral, pisiform, trapezium, trapezoid, capitate, and hamate — and five metacarpal bones —the first, second, third, fourth, and fifth metacarpal bones. [ 8 ]
wrist, complex joint between the five metacarpal bones of the hand and the radius and ulna bones of the forearm. The wrist is composed of eight or nine small, short bones (carpal bones) roughly arranged in two rows.
See anatomy pictures of the 27 bones in the hand and wrist, how they are connected with tendons and muscles and the nerves that run through the skeletal structure.
