It plays a vital role in motor and sensory functions, controlling the muscles of the shoulder, arm, and hand, and providing sensation in these areas. Understanding its anatomy is crucial for diagnosing and treating various injuries and conditions that can affect the upper limb's functionality.Anatomy of the Brachial PlexusThe brachial plexus is divided into five roots: C5, C6, C7, C8, and T1, which converge to form three trunks: upper, middle, and lower. These trunks further divide into divisions and cords before terminating in distinct nerves like the radial, median, and ulnar nerves. Each segment and its branches play specific roles in arm and hand movement, which is why an injury to any part of the plexus can result in distinct deficits. A brachial plexus diagram can be a helpful visual aid in understandin...
