There are six divisions that arise from the three trunks of the brachial plexus - three anterior divisions (one for each trunk) and three posterior divisions (one for each trunk). The divisions then merge, forming the cords of the brachial plexus.

Identify each division:

  • Anterior division of the superior trunk
  • Posterior division of the superior trunk
  • Anterior division of the middle trunk
  • Posterior division of the middle trunk
  • Anterior division of the inferior trunk
