The deltoid is innervated by this nerve named for the region inferior to the deltoid itself. 

Axillary Nerve

100

Located on the posterior scapula, this muscle's primary function is external rotation of the shoulder. 

Teres Minor

100

Both of these muscles work together to pull the scapula toward the spine and provide stability to the scapula. 

Rhomboid Major and Minor

100

This structure brings all of the blood from the neck and above back to the heart.

Superior Vena Cava

100

Located in the axilla, these structures might "drain" you, but that's a good thing.

Lymph Edema

200

This nerve is a terminal branch of the lateral cord in the brachial plexus and innervates the elbow flexors.

Musculocutaneous Nerve

200

This muscle's action is protraction and elevation of the scapula. Also known at the "boxer's muscle".

Serratus Anterior
200

Not an actual muscle, this structure attaches the lats to the gluteus maximus.

Thoracolumbar Fascia

200

This valve prevents backflow into the right atrium.

Tricuspid Valve

200

Boutonniere's Deformity is an injury to this structure in the finger. 

Central Slip or Central Band

300

The triceps brachii is innervated by this nerve which also innervates the extensor muscles in the forearm.

Radial Nerve

300

The action of this muscle is to flex the elbow, but it's strongest when the thumb is upward. Hopefully, you have this answer hammered down.

Brachioradialis

300

While not part of the rotator cuff muscles, this "lat's little helper" still assists with multiple actions of the shoulder. 

Teres Major

300

This structure carries deoxygenated blood from the heart muscles to the right atrium.

Coronary Sinus

300

This muscle is needed to lower your arm after asking a question in class. It also originates on a structure with a similar name.

Coracobrachialis

400

The flexor carpi ulnaris is a part of the wrist flexor group, but has a completely different innervation provided by this nerve.

Ulnar Nerve

400

The only muscle that flexes the DIP joints. Also gives you a strong grip!

Flexor Digitorum Profundus

400

This muscle is the most lateral of the erector spinae muscles. 

Iliocostalis

400
This structure delays the electrical signal of the heart to allow the atria time to empty. 

AV Node

400

"It might sound crazy, but it ain't no lie"- This is probably NSYNC's favorite muscle.

Lumbricals

500

This is the lats favorite nerve from the brachial plexus, probably because it innervates them. 

Thoracodorsal Nerve

500

One of two muscles whose action is ulnar deviation. This particular muscle is located on the posterior portion of the forearm.

Extensor Carpi Ulnaris

500

These muscles help elevate and depress the ribs for breathing. You may name only 1 of the 2. 

Serratus Posterior Superior or Inferior

500

This artery of the heart carries oxygen-rich blood to the left atrium and back and left side of the left ventricle. 

Circumflex Artery

500

The total number of bones in the hand. I'll give you minute, maybe less than 30 seconds.
