What is the name of the large bone in the upper arm?

The large bone in the upper arm is known as the humerus. It plays a crucial role in the mobility and function of the arm, connecting the shoulder to the elbow. The humerus generally has a rounded head that fits into the shoulder socket, allowing for a wide range of motion. It also has important sites for muscle attachment, enabling various arm movements, such as lifting and pushing. Understanding the function and structure of the humerus is essential, particularly when studying how different bones work together in the musculoskeletal system.

The radius and the tibia are both long bones of the forearm and lower leg, respectively, while the femur is the thigh bone. Each bone has specific locations and functions in the body, reinforcing the significance of knowing anatomical terminology and relationships.
