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.
Wrist bones. Your wrist is a complex joint made of eight bones that are arranged into two rows. The proximal row (on the back of your hand, closest to your forearm) includes the: Scaphoid. Lunate. Triquetrum. Pisiform. The distal row (on the underside of your wrist closest to your palm) includes the: Trapezium. Trapezoid. Capitate. Hamate.
There are two long bones in the forearm, and together they connect the upper arm to the wrist and hand through the elbow and wrist joints: Ulna (2): It is the longest and overall larger of the two bones, lying on the side of the pinky finger. This bone has two important landmarks, the coronoid process and the olecranon.
In this article, we will see the details of wrist anatomy with their parts, functions & diagrams. The carpal bones are eight tiny bones in your wrist that link it to your forearm. They are essential for wrist mobility. They connect with the bones in your forearm to facilitate smooth motion.
Each hand contains 27 distinct bones that give the hand an incredible range and precision of motion. The forearm's ulna and radius support the many muscles that manipulate the bones of the hand and wrist.
Overview of the bones that define the forearm, the radius and ulna. Extending from the wrist to the elbow joint is the region of the upper extremity called the forearm (antebrachium). The forearm helps the shoulder and the arm in force application and the precise placement of the hand in space, with the help of the elbow and radioulnar joints.
Bones have many shapes and sizes and are important to add structure to the body and protection to the vital structures. The bones have a crystalline construction embedded with mineral and live cells that maintain and repair the skeleton. Jump to: The scapula, or “shoulder blade,” is an approximately triangular shaped bone.
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.
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.
Describe the anatomy of the joints, ligaments, muscles, blood, and nerve supply that comprise the forearm, wrist, and hand. Describe the biomechanics of the forearm, wrist, and hand, including open- and close-packed positions, normal and abnormal joint barriers, and stabilizers.
