Ulna and Radius: Anatomical Structure and Functional Significance
The ulna and radius are the two long bones of the forearm, working together to facilitate a wide range of movements in the arm and hand. Positioned with the ulna on the medial side and the radius on the lateral side, these bones are connected by an interosseous membrane, ensuring coordinated function. Their anatomical structure is critical for professionals in fields like orthopedics, physical therapy, and sports medicine. This article provides an in-depth exploration of the ulna and radius, detailing their anatomical features from both anterior and posterior perspectives, as well as their physical roles in forearm mobility and stability.
Humerus and Elbow Joint: Anatomical Structure and Functional Role
The humerus, the single bone of the upper arm, plays a vital role in connecting the shoulder to the forearm, forming the elbow joint alongside the radius and ulna. This long bone facilitates a wide range of movements, from lifting to throwing, while providing structural support to the upper limb. Understanding the anatomical structure of the humerus and its articulation at the elbow joint is essential for professionals in orthopedics, physical therapy, and sports medicine. This article provides a comprehensive overview of the humerus and elbow joint, detailing their anatomical features and physical significance in human movement.
