There are many different bones, muscles and ligaments in the hand and wrist, enabling you to make precise and complex movements.
The wrist consists of eight small bones, called the carpal bones, plus two long bones in the forearm – the radius and ulna. The carpal bones are arranged into two groups of four:
Within the hand are the:
Where two bones meet are the joints. Each finger has three joints:
Cartilage covers the end of the bones in the joint, lubricated by synovial fluid. This allows them to glide smoothly over one another as the joints move.
Ligaments connect the bones, helping to support them and provide stability. The ligaments in the hand include:
Tendons connect muscles to bone. Among the tendons in the hand are the superficialis, profundus, extensor, flexor, extensor pollicis brevis and abductor pollicis longus.
