Study Notes

Brachial Plexus Overview

Composed of roots from spinal nerves C5 to T1.
Mnemonic for components: "Roots Reach To Drink Cold Beer" representing Roots, Trunks, Divisions, Cords, Branches.

Components of the Brachial Plexus

Roots:
- C5, C6, C7, C8, T1.
Trunks:
- Upper (C5-C6), Middle (C7), Lower (C8-T1).
Divisions:
- Each trunk splits into anterior and posterior divisions.

Visualization Techniques

Draw three Y's, with the middle Y facing the opposite direction.
Use two E's (Σ) for additional structure representations.
Place an X between C5/6 and C7 for clarity in root connections.

Terminal Branches

Musculocutaneous nerve: Most important branch.
Axillary nerve: Key branch for shoulder regions.
Median nerve: Vital for hand function.
Radial nerve: Important for arm extension.
Ulnar nerve: Significant for hand grip and dexterity.

Clinical Note

Knowledge of terminal branches is critical as damage can lead to specific dysfunctions.
Damage to the long thoracic nerve causes scapular winging, notably referenced by "C5,6,7 wings to heaven."
