What is the name of the 5 long bones that form the palm of the hand?

The five long bones that make up the palm of the hand are known as the metacarpals. Each metacarpal bone corresponds to a digit (finger) and plays a crucial role in providing structure and support to the hand, allowing for a range of movements and dexterity. The term "metacarpal" specifically refers to the bones located between the carpal bones of the wrist and the phalanges (the bones of the fingers).

Understanding the skeletal structure of the hand is vital for estheticians because it helps in grasping the functionalities of hand movements and their implications during treatments and procedures. This anatomical knowledge aids in performing techniques safely and effectively, especially in areas like massage or skincare where hand mobility is essential.

The other terms mentioned, such as phalanges, tendons, and ligaments, refer to different anatomical structures. Phalanges are the bones of the fingers themselves, tendons are the connective tissues that attach muscles to bones, and ligaments connect bones to other bones, contributing to the stability of the hand but not forming its structure directly. Hence, knowing that metacarpals are the direct answer is important for understanding the hand's anatomy and its functions in esthetics.
