CARPAL BONE Meaning and
Definition
-
Carpal bones are a group of eight small bones located in the wrist region of the human body. These bones form the skeletal framework of the wrist joint and are arranged in two rows, known as the proximal and distal rows.
The proximal row of carpal bones consists of four bones namely the scaphoid, lunate, triquetrum, and pisiform. The scaphoid bone is the largest carpal bone in the proximal row and is located on the thumb side of the wrist. It plays a vital role in wrist movement and stability. The lunate bone is positioned next to the scaphoid bone on the thumb side and helps facilitate smooth wrist motion. The triquetrum bone is situated adjacent to the lunate bone on the pinky side, while the pisiform bone is the smallest carpal bone that lies anteriorly to the triquetrum.
The distal row of carpal bones comprises four bones, including the trapezium, trapezoid, capitate, and hamate bones. These bones are positioned just below the proximal row and are responsible for connecting the wrist to the hand. Each of these bones contributes to the overall flexibility and stability of the wrist joint.
Overall, carpal bones play a crucial role in providing support, strength, and flexibility to the wrist joint, enabling various movements and functions of the hand and forearm.
