The brachial plexus is broken up into these 5 segments.

What are; Roots, Trunks, Divisions, Cords and Branches

100

These nerve roots come together to make the Phrenic nerve

What are the C3, C4 and C5 nerve roots

100

The medial and lateral cords each have this type of nerve coming off of them.

What is a Pectoral Nerve

100

The lateral cord becomes this, and then turns into this.

What is the Musculocutaneous nerve, and the Lateral Ante Brachial Cutaneous Nerve

100

These are the borders of the Quadrangular Space

What are Teres Minor (Sup), Teres Major (Inf), Neck of Humorus (Med), and the Long Head of Triceps (Lat)
200

These are the 3 trunks of the brachial plexus

What are Superior, Middle, Inferior

200

The nerve roots of C5, C6 and C7 come together to make this

What is the Long Thoracic Nerve

200

The posterior cords has these 3 parts of the same nerve coming off of it.

What is the Upper, Middle and Lower Subscapular Nerve
200

The Median Nerve turns into this

What is the Anterior Interosseous Nerve

200

These are the borders of the Triangular Interval

What are the Long Head of Triceps (Sup), Teres Major (Med) and Lateral Head of Triceps (Lat)

300

These are the 3 cords of the brachial plexus

What are Lateral, Posterior and Medial
300

This nerve comes off of the C5 nerve root

What is the Dorsal Scap Nerve

300
The Cords are located deep to this, and the names of the cords are in relation to this

Deep to Pec Minor, and in relation to their location around the Axillary Artery

300

The nerve comes off of the Posterior cord and innervates these muscles

What is the Axillary Nerve, and innervates Teres Minor and the Deltoid

300

After the Triangular Space the Radial Nerve travels through this

What is the Radial Groove (aka Musculo-Spiral Groove)
400

The medial and lateral cords come together to make this nerve

What is the Median Nerve

400
These are the 2 nerves to come off of the superior trunk

What are the Suprascapulus Nerve and the Nerve to Sub-Clavious

400

These 2 nerves come off of the Medial Cord

What are the Medial Brachial Cutaneous Nerve (arm) and the Medial Ante Brachial Cutaneous Nerve (forearm)

400

The Ulnar Nerve is found traveling alongside these

What are the Brachial Artery and the Median Nerve
400

The Radial Nerve splits into these after it leaves the Radial Tunnel

What are Deep (motor) and Superficial (sensory) nerves. 

500

The Radial Nerve comes off of this cord

What is the Posterior cord

500

This is the most important Nerve Root in the Phrenic Nerve

What is the C4 nerve root. Injury leads to needing a ventilator.

500

The Upper and Middle Subscapular Nerve both innervate this muscle, and the Lower one innervates this muscle.

What is the Subscapularis Muscle, and what is Teres Major.

500

The Musculocutaneous Nerve pierces this muscle

What is Coracobrachialis

500

The Median Nerve travels through this in the arm and this in the hand

What is the Cubital Fossa and the Carpel Tunnel
