What bones are found in the arm and forearm?

The bones found in the arm and forearm include the humerus, ulna, and radius. The humerus is the long bone that makes up the upper arm, extending from the shoulder to the elbow. The ulna and radius are the two bones that make up the forearm. The ulna is located on the medial side of the forearm when in the standard anatomical position and is larger at the elbow joint, while the radius is on the lateral side and connects to the wrist.

This combination of bones allows for a wide range of motion in the arm and is essential for various activities involving the upper extremity, such as lifting, pushing, and pulling. Understanding the structure and relationship of these bones is crucial for studying human anatomy, especially in the context of fields related to health and medicine.
