These bones are often referred to as the palm bones, and they play a crucial role in the functionality of the hands. While the term 'metacarpal bone' is commonly used, there are alternative names to describe these bones, including metacarpus, metacarpale, and ossa metacarpalia. Additionally, they are at times referred to as the intermediate hand bones.
