Elbow and wrist extension, artwork C016 / 6792
Elbow and wrist extension. Artwork of the muscles of the arm from the front, with red arrows showing the direction of movement when extending the elbow and wrist joints. Elbow extension is the straightening of the arm from a bent position (here from 90 degrees downwards), a motion performed mainly by the triceps brachii muscle on the underside of the upper arm. Wrist extension (sometimes called dorsiflexion) is where the hand is tilted in the direction of the back of the hand, as opposed to palmar flexion. The nerve used is the radial nerve. This is the left arm. For the right arm, see C016/6791

EDITORS COMMENTS
This print showcases the intricate details of elbow and wrist extension in the human arm. The artwork, labeled as C016 / 6792, provides a comprehensive visual guide to understand the muscles involved in extending these joints. The image depicts the front view of a left arm against a clean white background. Red arrows elegantly highlight the direction of movement when extending both the elbow and wrist joints. Elbow extension refers to straightening the arm from a bent position, primarily facilitated by the triceps brachii muscle located on the underside of the upper arm. In addition to elbow extension, this artwork also focuses on wrist extension or dorsiflexion. It demonstrates how tilting one's hand towards their backhand is considered wrist extension rather than palmar flexion. The radial nerve plays a crucial role in enabling this movement. With its emphasis on anatomy and physiology, this illustration offers valuable insights into normal range of movements within our musculoskeletal system. It highlights various components such as tendons, ligaments, and biomechanics that contribute to healthy mobility. D & L GRAPHICS / SCIENCE PHOTO LIBRARY has skillfully captured this moment with precision and clarity. This print serves as an educational resource for biology enthusiasts, medical professionals, or anyone interested in understanding human body mechanics at an anatomical level.
