How to Draw the Brachial Plexus Using 3

How to Draw the Brachial Plexus Using 3 Y’s, 1 M, 1 X, and a Backslash (). Jennifer M. Burgoon, Ph. D Assistant Professor – Clinical Division of Anatomy Department of Biomedical Education & Anatomy College of Medicine The Ohio State University Columbus, Ohio

How to Draw the Brachial Plexus Objective of Presentation: • To demonstrate an easy and efficient means to draw a basic brachial plexus using 3 Y’s, 1 M, 1 X, and 1 (i. e. , a back slash) • To demonstrate the terminal and non-terminal branches on a basic brachial plexus drawing. Instructions for Presentation: Download and view this Power. Point presentation as a ‘Slide Show’ to fully experience the construction and labeling of the brachial plexus. By: Jennifer M.

How to Draw the Brachial Plexus Definition of the Brachial Plexus: A nerve network formed by the ventral rami of spinal nerves C 5, C 6, C 7, C 8, and T 1; branches of this plexus innervate the upper limb. By: Jennifer M. Burgoon, Ph. D The Ohio State University

How to Draw the Brachial Plexus Directions to Draw Brachial Plexus: 1. Draw 3 horizontal Y’s that are parallel; the upper and lower Y’s should open to the right, while the middle Y should open to the left. 2. Draw 1 M on the left connecting the upper and lower Y’s; the M should open to the left; be sure the M has a long central portion. 3. Place 1 X between the upper and middle Y’s. 4. Place 1 (i. e. backslash) between the middle and lower Y’s. 5. Label. By: Jennifer M. Burgoon, Ph. D The Ohio State University

How to Draw the Brachial Plexus Non-Terminal Branches: There a number of nerves that branch off the brachial plexus not at its termination, but instead these branches come off the roots, trunks, and cords of the brachial plexus. The remaining slides show these non-terminal branches. By: Jennifer M. Burgoon, Ph. D The Ohio State University
