Add the muscles of the anterior compartment of the arm.

	Step 20: Add the coracobrachialis.
	Step 21: Add the brachialis.
	Step 22: Add the biceps brachii.
	Step 23: Add the clavicles.
	Step 24: Add the deltoid muscles.

Now add the superfical veins of the arm.

Step 25: Add the cephalic vein.

Notice the relationship of the major arteries and veins of the shoulder to the clavicle.

	Subclavian central lines are often utilized in emergency rooms and in intensive care units. These are often placed at the beside. What landmarks would a physican use for placement?
Middle third of the clavicle is where the subclavian vein is directly under the clavical. Aiming the insertion needle toward the sternal notch establishes the proper angle for insertion. Try it by rotating the cadaver and pretending to introduce a needle under the clavicle.
	What are the potential complications of bedside subclavian central line placement?
Pneumothorax, hemothorax, bleeding and infection.

	Step 26: Add the pectoral vein and thoraco-acromial artery.
	Step 27: Add the pectoralis major which has two heads (clavicular and sternal).
