Brachial Plexus — Fill In the Drawn Diagram

Roots → trunks → divisions → cords → terminal branches, plus all 11 collateral branches. Mini branches fan above and below so nothing overlaps the main diagram.

Roots Trunks Ant. Division Post. Division Cords Terminal Branches Collateral Branches
Level 1

Roots → Trunks

Roots and their connections are drawn. Fill in the blanked root and trunk labels.

Level 2

Trunks → Divisions

Roots and trunks shown. Fill in the blanked divisions — line color is your clue (black = anterior, gold = posterior).

Level 3

Divisions → Cords

Roots, trunks, divisions shown. Fill in the blanked cords.

Level 4

Cords → Terminal Branches

Everything through cords is shown. Fill in the blanked terminal branches.

Level 5 — The Real Test

Full Blank — Main Column

Every main column label is blank. Collateral branches shown as reference scaffolding.

Tackle this after Levels 1–4 feel solid.

Level 6 — Collateral Branches

Mini Branch Drill

Main column is shown as scaffolding. Only the collateral branch names are blanked. Trace the dashed line back to its origin.

Purple dashed lines = collateral branches. Origin level is the key clinical fact — trace each line back before guessing.
Level 7 — Everything Blank

Full Blank — Main Column + All Collaterals

Every label is blank. The hardest drill.

Only attempt after Level 6 feels comfortable.

Work through Levels 1 → 7 in order. Level 7 is meant to feel hard — that's the point.
