RADIALIS Meaning and
Definition
-
Radialis is a Latin word that translates to "radial" in English. In anatomy, it refers to structures that are associated with or located in the radial aspect of the body. The term is often used to describe specific muscles, nerves, arteries, and veins found in the forearm, wrist, and hand region.
The radial muscle, known as musculus radialis in Latin, is a long and prominent muscle located on the lateral side of the forearm. It extends from the upper arm bone (humerus) to the wrist, where it plays a crucial role in flexing and stabilizing the wrist joint.
Radialis is also associated with the radial nerve, also called nervus radialis, which is one of the major nerves in the upper limb. Originating from the brachial plexus, it runs along the radial side of the arm, crosses the elbow joint, and then descends along the radial aspect of the forearm. This nerve is responsible for transmitting motor signals to the muscles of the posterior compartment of the arm and forearm, allowing for movement and sensation in these areas.
Additionally, there are various arteries and veins that are named "radialis" due to their relation to the radial aspect of the forearm. These blood vessels supply oxygenated blood to the muscles and tissues in the region, and their proper functioning is essential for normal physiological processes in the arm and hand.
