Study Notes

Cardiac Health and Anatomy

A 47-year-old man with chronic atrial fibrillation returns to his cardiologist for a follow-up, highlighting the importance of the right atrium, which contains the SA node.

Superior Mediastinum Anatomy

The superior mediastinum contains the left recurrent laryngeal nerve.
The superior mediastinum does not contain the coronary arteries.

Brachiocephalic Vein Anatomy

The left brachiocephalic vein does not receive the accessory hemiazygos vein.

Ligamentum Arteriosus

The ligamentum arteriosus attaches the aorta to the pulmonary artery.

Bronchial Anatomy

Right main bronchus is wider and has a more vertical course than the left main bronchus.

Hilum Components

All of the following are parts of the hilum, except the superior vena cava.

Arterial Anatomy

The external iliac artery becomes the femoral artery as it passes under the inguinal ligament.

Femoral Artery Branches

The deep artery of the thigh has lateral and medial circumflex femoral branches and three perforating branches.

Popliteal Artery

The popliteal artery originates anterior and posterior tibial arteries.
