What is the brachial plexus?

The brachial plexus is indeed a network of nerves. This intricate formation is responsible for transmitting signals between the spinal cord and the muscles and skin of the shoulder, arm, and hand. It originates from the upper five cervical nerves (C5-C8) and the first thoracic nerve (T1), merging to form several trunks and cords that branch out into distinct peripheral nerves. These branches innervate muscles and provide sensory function to various regions of the upper limb, which is crucial for both movement and sensation.

Understanding the role of the brachial plexus highlights its significance in orthopedic practice, as injuries or conditions affecting this nerve network can lead to considerable functional impairment in the arm and hand. This underscores the importance of recognizing and properly addressing issues related to the brachial plexus in clinical assessments and treatments.
