The anatomy of the airway is incredibly important and fairly simple. The structures of the trachea and bronchi are adapted tubes that don't collapse with changes in pressure, and the mucociliary escalator has an important protective role.

The mediastinum is a region within the thorax between the lungs. In here we find the heart, great vessels, trachea, oesophagus and other anatomical structures. We can further describe where these structures are by dividing the mediastinum up into superior and inferior parts, and the inferior mediastinum up into anterior, middle and posterior medastinal compartments.

The anatomy of the superior vena cava and inferior vena cava in 5 minutes, with a little extra about anastomoses. These are the largest and some of the most important veins in the body.

How do skeletal muscle cells (myocytes) change their length? How does this relate to the different types of contractions that we see in gross anatomy and rigor mortis?

The parathyroid glands are vital as they help regulate blood calcium levels. Where are they?

Is the amygdala the fear centre of the brain? What's the anatomy here?

The sinoatrial node is the pacemaker of the heart. Let's talk about it in a little more detail.

The saphenous veins are superficial veins of the lower limbs. Why do they become varicose veins and why are they used in CABG surgery? What is CABG?
