Question

Anatomy Tutorial: Anatomy of the Heart

Answer 1

note: my professor requires us to memorize these diagrams. I will only be focusing on the location and structure of these components, not their functions, for memorization purposes.

Answer 2

first I will start by labelling the fatty deposits. the one in between the ventricles is the anterior interventricular sulcus and the other, off to the side, is known as the coronary sulcus

Answer 3

the long, vertical tube is the vena cava which has inferior and superior openings

Answer 4

next, I will add two structures known as the auricles (from the Latin auricula meaning ear, because these are shaped like dog ears)

note that this is the anterior view of the heart so the right atrium is on the left side of the diagram

Answer 5

these two structures are known as the aorta and pulmonary artery. knowing the locations of these two major structures will guide the next labels



the bulky part of the pulmonary artery is given the label "pulmonary trunk" whereas the label closer to the opening is the left pulmonary artery ((a)rtery --> leading (a)way from the heart)

Answer 6

the ascending and descending branches are labelled accordingly while the main body of the aorta is given the label "arch of the aorta"

now, the hardest part is memorizing the three openings at the top of the aorta

going from left to right:
1. the brachiocephalic trunk
2. the Left common carotid artery
3. the Left subclavian artery

if you can remember BCS (alphabetical order) it will be easier to memorize the order of these structures
