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.

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

Brachial plexus
The brachial plexus is a group of nerves that originate from the neck region and branch off to give rise to most of the nerves that control movement in the upper limb. Injuries to the brachial plexus are common and can be debilitating. If the injury is severe it can cause weakness or paralysis of the entire upper limb.
