The term "metacarpal" refers to the five long bones located in the middle part of the hand, between the wrist and the fingers. Each metacarpal bone connects to a finger and plays a crucial role in hand movement and function. They are numbered from one to five, starting with the thumb as the first metacarpal. Metacarpals are classified as long bones and are essential for gripping and manipulating objects. They provide structural support and stability to the hand, allowing for a wide range of motions. Injuries to the metacarpals, such as fractures, can significantly impact hand function and require medical attention.
