Video from VB Anatomy on YouTube

6.3.3 Draw the brachial plexus, showing its roots, trunks, divisions, cords and branches with their root values, and describe the relations of the cords to the axillary artery.

Why this video

It explains how to diagram the roots, trunks, divisions, cords, and branches with their root values, and includes a dedicated section detailing how the cords relate to the axillary artery.

Heads up

Check the root value of the ulnar nerve against your course convention, as many standard sources omit the C7 communicating contribution.
