How to Draw the Brachial Plexus

Directions

This PowerPoint presentation is animated, such that the appearance of image components and transitions between slides will occur automatically. Alternatively, clicking on the left mouse button will advance the presentation.

Educational Purpose

This brief, animated PowerPoint presentation guides anatomy students through the process of making a simple drawing of the brachial plexus. This “mnemonic drawing” can help students learn the basic parts of the brachial plexus and serve as a first step in understanding this clinically important nerve network.

Begin with a letter “Y”, an “I” and a “Y”.

Add a “strike” and a “spare” (bowling scorekeeping symbols)

Draw “arches”.

Draw horizontal lines to separate the parts.
