This 16-piece, full-sized anatomical model shows the position of the brachial plexus nerves relative to surrounding bones, muscles, and arteries.

The brachial plexus is a network of nerves in the shoulder that carries movement and sensory signals from the spinal cord to the arms and hands. This model is designed for use as a clinical education tool, specifically for ultrasound guided nerve blocks and anesthesia for surgery.
The model can be used upright or in supine. You can print either shoulder or both. Use different coloured filament to emphasis structures.
The “Brachial Plexus” includes all roots, trunks, divisions, cords and branches, as well as proximal portions of the suprascapular and long thoracic nerve. The phrenic nerve is included as well, not because it is a part of the brachial plexus, but because it is a structure to identify and avoid when doing nerve blocks or surgery in this area.
The main structural pieces are attached with magnets. To assemble both sides with magnets, you will need 36 1/4” x 1/8” (6mm x 3mm) cylindrical neodymium magnets. www.kjmagnetics.com is a good source of magnets. Pieces can be glued together for permanent attachment.
The roots of the brachial plexus and phrenic nerve are attached via insertion holes in the intervertebral foramen. The brachial plexus and subclavian/axillary artery are also held in place by the clavicle.
The following pieces form the structural base:
• Spine Base
• Right and/or Left Scapula Rhomboid Base
• Sternum Rib Base
• Right and/or Left Clavicle
The follow pieces are non-structural. Print the pieces and sides that you need.:
• Head of Humerus
• Anterior Scalene
• Brachial Plexus
• Phrenic Nerve
• Subclavian/Axillary Artery
This is an advanced print requiring knowledge in setting up supports and post-print cleanup.
