Which bone is commonly referred to as the humerus?

The humerus is indeed commonly known as the long bone of the upper arm. It plays a crucial role in connecting the shoulder to the elbow and serves as a key attachment point for various muscles that facilitate movement of the arm. Its structure is designed to withstand the forces exerted during activities such as lifting and throwing, making it essential for upper limb function. Understanding the role of the humerus in the anatomy of the arm is important for those who work with orthotics, as many devices may be designed to support, stabilize, or enhance the movement of the structures around this bone. This knowledge is foundational in ensuring the effective fitting and use of orthotic devices for patients.
