"What's Wrist Flexion?"

By Joseph WilliamsMarch 17, 2026

Wrist flexion, a term often used in anatomy and physiology, refers to the bending motion of the wrist that allows the palm of your hand to face upwards. This movement is crucial for various daily activities, such as typing, writing, or shaking hands. But what exactly is wrist flexion, and how does it work? Let's delve into the intricacies of this essential wrist motion.

Understanding Wrist Flexion: The Basics

Wrist flexion is a type of movement known as a flexion, which is a bending movement that decreases the angle between the bones. In the case of the wrist, this means that the wrist bends in the direction of the palm, towards the forearm. The opposite movement, where the wrist bends downwards, is called wrist extension.

If you experience severe pain, swelling, or difficulty moving your wrist, or if these symptoms persist for more than a few days, it's a good idea to consult a healthcare professional. They can help determine the cause of your symptoms and recommend appropriate treatment.
