The radial nerve is a major peripheral nerve of the upper limb responsible for extension of the elbow, wrist, and fingers. This anatomy diagram of the anatomical course of the radial nerve traces its origin from the posterior cord of the brachial plexus, its spiral course along the radial groove of the humerus, and its division into superficial and deep branches near the elbow. It highlights its close relationship with the humeral shaft, explaining its vulnerability in mid-shaft fractures. The diagram also illustrates sensory supply to the posterior arm, forearm, and dorsum of the hand. Understanding this nerve pathway is crucial for evaluating wrist drop and upper limb trauma in clinical practice.
