How to draw Brachial Plexus?

These are several nerve plexuses in our body. The four main nerve plexuses are the cervical plexus, brachial plexus, lumbar plexus, and the sacral plexus. The choroid plexus in brain is a part of the central nervous system which consists of ventricles, capillaries, and ependymal cells. After reading this article, you will have a clear idea on how to draw Brachial Plexus and how to remember them easily. 

You can remember them with a picture shown above – ‘Tree and Swing’

  1. Roots of tree – Five nerve roots are the five anterior primary rami of the spinal nerves
  2. Trunk of tree – Roots merge to form the trunks
  3. Trunk divides in tree – Each trunk then splits in two, to form six divisions
  4. Cords of the swing – These six divisions regroup to form the three cords or large fiber bundles
  5. Then most branches arise from cords (In above image, you have to remember the branches part separately)
You can get access to our Medical Resources Library to get access to more than 300 medical presentations and all other medical resources that will be helpful for your entire career. 

Follow these steps to draw Brachial Plexus

1) Draw the Roots

First write nerve roots C5, C6, C7, C8 and T1 one below another.

2) Draw the Trunks

  • Join the C5 and C6 to form Superior Trunk/Upper Trunk
  • C7 continues alone as Middle Trunk
  • Join C8 & T1 to form Inferior Trunk/Lower Trunk

3) Draw the Divisions

From each Trunk, draw Anterior Division and Posterior Division. You have to draw 6 divisions. 

4) Draw the Cords

  • Join Anterior Division of Superior Trunk and Anterior Division of Middle Trunk to form Lateral Cord
  • Join all three Posterior Divisions of Superior, Middle and Inferior Trunks to form Posterior Cord
  • Anterior Division of Inferior Trunk continues as Medical Cord

5) Draw the Branches

  • Long thoracic nerve – Arises from the anterior rami of C5, C6 and C7 nerve roots
  • Suprascapular nerve – Arises from superior trunk
  • Radial nerve – Originates as a terminal branch of the posterior cord of the brachial plexus.
  • Axillary nerve – Originates from the posterior cord of the brachial plexus.
  • Ulnar nerve – Arises from the medial cord of the brachial plexus
  • Median nerve – Arises from the branches from medial and lateral cords of the brachial plexus
  • Musculocutaneous nerve – Arises from the lateral cord of the brachial plexus
