The scaphoid bone is located on the radial side of the wrist and is the largest bone in the proximal row of carpal bones. It is shaped like a boat, which gives it its name. The scaphoid bone serves as a link between the wrist and hand bones, and it is one of the most commonly fractured bones of the wrist in children.

The image and name of the trapezium bone

The trapezium bone is located in the distal row of carpal bones, closer to the hand. It is named after its almost square shape and plays a significant role in the movement of the thumb. This bone articulates with the first metacarpal bone, which forms the base of the thumb joint.

The image and name of the trapezoid bone

The trapezoid bone is a small bone located next to the trapezium bone in the distal row of carpal bones. It is named after its trapezoid shape and functions primarily to support the wrist and strengthen the hand.

The image and name of the lunate bone

The lunate bone is located in the center of the wrist, between the scaphoid and triquetral bones. It is crescent-shaped and is the most commonly dislocated carpal bone in children. Its main function is to provide stability to the wrist joint and support the weight of the upper body.

The image and name of the triquetral bone

The triquetral bone is located on the ulnar side of the wrist and is named after its three-sided shape. It helps to support the wrist joint and provides attachment points for several ligaments and muscles.

The image and name of the pisiform bone

The pisiform bone is a small, pea-shaped bone on the ulnar side of the wrist. It serves as an attachment point for several ligaments and muscles that aid in the movement of the wrist and hand. This bone is not always present in children, and its development may vary.

The image and name of the radial styloid process

The radial styloid process is a bony projection located at the end of the radius bone, on the lateral side of the wrist. It serves as an attachment point for several ligaments and muscles and provides stability to the wrist joint.

The image and name of the ulnar styloid process

The ulnar styloid process is a bony projection located on the end of the ulna bone, on the medial side of the wrist. It serves as an attachment point for several ligaments and muscles and helps to provide stability to the wrist joint.

The image and name of the wrist joint

The wrist joint is a complex joint composed of multiple bones, ligaments, and tendons. It allows for a wide range of motion, including flexion and extension, abduction and adduction, and circumduction. The wrist joint is essential for performing everyday tasks such as writing, holding objects, and playing sports.

The image and name of the radiocarpal joint

The radiocarpal joint is the articulation between the distal end of the radius bone and the proximal row of carpal bones. It is responsible for wrist flexion and extension and provides stability to the wrist joint.

The image and name of the midcarpal joint

The midcarpal joint is located between the proximal and distal rows of carpal bones and allows for wrist abduction and adduction. It is an essential joint for performing tasks that require wrist movement, such as playing musical instruments or using tools.

The image and name of the carpometacarpal joint

The carpometacarpal joint is the articulation between the distal row of carpal bones and the metacarpal bones of the hand. It is responsible for thumb movement and allows for gripping and holding objects.

The image and name of the intercarpal ligaments

The intercarpal ligaments are a group of ligaments that connect the carpal bones to one another. They provide stability to the wrist joint and limit excessive movement of the carpal bones while allowing for healthy wrist flexion and extension.

The image and name of the radiocarpal ligaments

The radiocarpal ligaments are a group of ligaments that connect the radius bone to the carpal bones. They provide support and stability to the wrist joint and allow for proper wrist movement.

The image and name of the ulnocarpal ligaments

The ulnocarpal ligaments connect the ulna bone to the carpal bones and provide additional stability to the wrist joint. They help to limit excessive movement of the carpal bones during wrist movement and ensure proper alignment.

The image and name of the extensor tendons

The extensor tendons originate from the forearm muscles and attach to the hand and wrist bones. They are responsible for extending the wrist, fingers, and thumb and allow for activities such as typing, writing, and playing sports.

The image and name of the flexor tendons

The flexor tendons originate from the forearm muscles and attach to the hand and wrist bones. They are responsible for flexing the wrist, fingers, and thumb and allow for gripping and holding objects.

The image and name of the carpal tunnel

The carpal tunnel is a narrow passageway located on the palm side of the wrist. It is formed by the carpal bones and a ligament and serves as a pathway for the median nerve and flexor tendons. In children, the carpal tunnel may be smaller due to their wrist's size, leading to carpal tunnel syndrome.

The image and name of the dorsal surface of the wrist

The dorsal surface of the wrist is the back of the hand, and it contains several important structures such as tendons, ligaments, bones, and nerves. It is an essential area for wrist and hand movement and is vulnerable to injury during sports or other physical activities.

The image and name of the palmar surface of the wrist

The palmar surface of the wrist is the palm side of the hand and contains several important structures such as tendons, ligaments, bones, and nerves. It is also an essential area for wrist and hand movement and is vulnerable to injury.

The image and name of the flexor retinaculum

The flexor retinaculum is a band of fibrous tissue that stretches across the palm side of the wrist, creating the carpal tunnel. It provides support and protection to the contents passing through the tunnel, which includes the median nerve and flexor tendons.

The image and name of the extensor retinaculum

The extensor retinaculum is a band of fibrous tissue that stretches across the backside of the wrist, providing support and stability to the extensor tendons. It forms six compartments that help separate the tendons and prevent them from rubbing against each other during wrist movement.

The image and name of the radial artery

The radial artery is one of the major arteries supplying blood to the hand and wrist. It originates from the brachial artery, travels down the forearm, and enters the wrist through a narrow passageway known as the anatomical snuffbox. The radial artery is essential for providing oxygen and nutrients to the wrist and hand tissues.

The image and name of the ulnar artery

The ulnar artery is another major artery supplying blood to the hand and wrist. It originates from the brachial artery, travels down the forearm, and enters the wrist on the medial side. The ulnar artery is also important for providing oxygen and nutrients to the tissues of the wrist and hand.

The image and name of the median nerve

The median nerve is one of the three nerves that provide sensation and motor control to the wrist and hand. It travels through the carpal tunnel and supplies the palm side of the hand and fingers.

The image and name of the ulnar nerve

The ulnar nerve is another nerve that provides sensation and motor control to the wrist and hand. It travels along the ulnar side of the forearm and enters the wrist between the hamate and pisiform bones. The ulnar nerve supplies the little finger and half of the ring finger.

The image and name of the radial nerve

The radial nerve is the third nerve that provides sensation and motor control to the wrist and hand. It originates from the brachial plexus and supplies the back of the hand, thumb, and part of the index finger.
