Brachial Plexus is the most important topic one comes up against in their first year of medical study. This plexus has high importance as the body only has 5 spinal plexuses and this one is the most important One. Here we will discuss the mnemonics for brachial plexus but before that a short overview of what the brachial plexus is.
Overview of Brachial Plexus
The Brachial plexus consists of the spinal nerves of the anterior primary rami of C5, C6, C7, C8, so forth till T1. It also consists of the anterior primary rami of the C4 and T2 nerves. The Plexus extends from the spinal cord, passes through the cervico-axillary canal in the neck, over the first rib then into the armpit.
The plexus’s origin may shift one segment, upward or either downward, that results in a prefixed or postfixed plexus respectively.
- In the prefixed position, the contribution by C4 is larger and that from T2 is usually absent.
- In the postfixed plexus, the contribution by T1 is larger, T2 always present, C4 absent, and C5 is reduced in size.
Not going into more detail as you already know what the brachial plexus is if you are reading this, let us move on to the mnemonics
