Brachial plexus

  • Definition
    • The brachial plexus is a group of nerves that run from the lower neck through the upper shoulder area. These nerves provide the shoulder, arm, forearm, and hand with movement and sensation.

  • Information
    • Damage to the brachial plexus nerves can cause muscle and sensation problems that are often associated with pain in the same area. Symptoms may include:

      • Loss of feeling or sensation in your arm or hand
      • Trouble moving your arm
      • Lack of muscle control in the arm, hand, or wrist
