What is this article about?
The brachial plexus begins in the spinal cord at the cervical and upper thoracic region (from C5-T1) and is a system of nerves that relays messages to and from the central nervous system to your shoulder, arm and hand. It is a complex network that supplies the nerves to all the muscles in the upper limbs apart from the trapezius. If this web of nerves is damaged, it can have potentially severe consequences for the individual.
