Final answer:
The carpal bones in the proximal row of the wrist, from medial to lateral, are the pisiform, triquetrum, lunate, and scaphoid. The mnemonic 'So Long To Pinky, Here Comes The Thumb' can help remember the order of these bones.
Step-by-step explanation:
The carpal bones in the proximal row of the human wrist are arranged from lateral to medial as follows: scaphoid, lunate, triquetrum, and pisiform. These bones are crucial for the movement and stability of the wrist joint. The scaphoid, lunate, and triquetrum contribute to the formation of the radiocarpal joint, which allows the wrist to move in various directions. The pisiform, being positioned anteriorly to the triquetrum, forms a palpable bony prominence on the medial side of the hand.
A mnemonic that helps to remember the order of these bones is "So Long To Pinky, Here Comes The Thumb", which illustrates the arrangement starting from the thumb side (lateral) to the pinky side (medial) and then continues for the distal row of carpal bones in reverse direction.
