What is the name of the upper arm bone?

• A. Femur
• B. Tibia
• C. Humerus
• D. Radius

Answer: (C)

The upper arm bone is known as the humerus. It is a long bone that extends from the shoulder to the elbow, playing a crucial role in the structure and function of the arm. The humerus is responsible for connecting with the scapula at the shoulder joint and with the radius and ulna at the elbow joint, allowing for a wide range of motion in the arm. This connection is essential for various activities such as lifting, throwing, and reaching. Understanding the anatomy of the humerus is important for orthopedic technologists, as it is frequently involved in injuries, fractures, and conditions such as arthritis. Recognizing its role in the musculoskeletal system aids in the effective assessment and treatment of upper arm injuries.
