Discover A Simplified Approach to Master the Complexity of Anatomy with me, Dr. David Morton ... The Noted Anatomist!
------------------------------------------------------------------
This brief video tutorial discusses why the heart needs its own circulatory system, identifies the principle coronary arteries and cardiac veins and briefly discusses coronary dominance.
0:00. Introduction
0:19. What is the coronary circulation?
2:14. Function of coronary arteries
2:27. Coronary arteries are "end arteries" (at 3:19 i am sorry for my mistake ... cardiac arrest is NOT the same as a heart attack)
3:43. Right coronary artery (RCA)
- 5:04. Sinuatrial nodal (SA) artery
- 5:18. Right marginal artery (acute marginal artery)
- 6:01. Posterior descending artery (PDA)
- 6:50. Definition of coronary dominance (right dominant, left dominant, co-dominant)
- AV nodal artery
8:50. Left coronary artery (LCA)
9:33. Left anterior descending artery (LAD); Anterior interventricular artery
10:39. Left circumflex artery (LCX)
11:27. Left marginal artery (obtuse marginal artery)
12:01. Cardiac veins (coronary sinus, great cardiac vein, middle cardiac vein, small cardiac vein)
13:34. Regulation of blood flow in coronary circulation
14:15. In-a-nutshell
15:05. References

I had a stent placed in the RCA which was blocked 95% about 16 years ago. It was a fascinating procedure and I saw the blocked artery on the fluorscope screen before they pointed it out. The surgeon showed me all the equipment, guide wire etc. saying "you can touch them, it's your blood!" . I also got a before-and-after polaroid print which I use as a wallpaper on my computer to remind me not to let my cholesterol and blood pressure go as high as they did before the event. This is technology!

This is an excellent video. The pace is perfect, just enough humor, clear images and audio, and a nice balance of intermediate and beginner information. This is the first of your videos I have seen. I have a gross anatomy exam on the thorax in a few days and I think your videos are going to be a lot of help. Thank you!

@nixicat2480 8 лет назад

Thank yo for making these videos. It really helps to hear / see things more than once, so you let me reinforce what I learn in class each day!

@pradipneupane9767 4 года назад

Good explanation apart from a few misleading information: There is a clear difference between Heart attack (MI) and Cardiac Arrest. Myocardial Infarct (Heart Attack)is Death of cardiac muscle caused by prolonged severe ischemia where Cardiac arrest is when the heart malfunctions and suddenly stops beating unexpectedly. People often use these terms interchangeably, but they are not synonyms. A heart attack is a “circulation” problem and sudden cardiac arrest is an “electrical” problem.

@TheNotedAnatomist 4 года назад

I totally agree ... thanks Pradip for your insight and for watching the tutorial

@joestevenson5568 2 года назад

A cardia arrest can be expected. Its just when the heart stops beating/generating significant output. For any reason.

@youngswoll3 Год назад

Cardiac arrest isn’t always an electrical problem, an example would be PEA (pulseless electrical activity)

@SaurabhG1001 3 года назад

I had to refresh my heart anatomy quickly as i was entering clinicals and this is exactly what was looking for. I only had to look at it once and a light bulb went on in my head and most importantly this type of explanation and animation makes this stick in long term memory. Very easy to follow no chit-chat and stumbling it is wonderful and a pleasure to learn from. Great video please make more and thank you for your time and effort. AJ

I'm ashamed to say I had no idea these were the arteries and veins that they're talking about when you hear about someone having bypass surgery. I've always thought they were talking about the aorta or inferior/superior vena cava. Watched a bypass surgery video and it was completely different from what I thought. Great video-very well described. Thanks!

The videos are very explanatory and informative! I would like to thank and congratulate the Doctors and all the people involved that made it possible!

@samanthawilmeth7701 7 лет назад

@damnedforever2 5 лет назад

Cardiac arrest is a complete arrest of the electrical function in the heart where it can't pump blood effeciently and in which causes instant death. Myocardial infarction is a blockage of one of the coronary arteries which then blocks oxygen to the heart and cause ischemia or muscle death. MIs can lead to cardiac arrest but two different things.

@wholeNwon 5 лет назад

Cardiac arrest actually refers to the cessation of the mechanical function of the heart and it can occur with preservation of some electrical activity. MI refers to the death of muscle due to the obstruction you described. Ischemia is not muscle death though muscle may be viable and still asystolic.

@analogsynthplayer 4 года назад

wholeNwon Exactly. Thank you for clarifying that. Electrical precedes mechanical. Treat your patient, not their ekg

@RiXFortuna 3 года назад

I might be wrong but looks like he didn’t wrote ischemia “is” muscle death, he used “or”

@MrNihak 8 лет назад

Wonderful, don't hesitate to explain why they are named like that (marginal for at the marge), it's extremely helpful ! Thank you a lot

@hollycahill3901 Год назад

Amazing video. Very clear and concise while easy to understand

@memoore7821 7 лет назад

Really nice video. I did want to mention that you said that the AV node was nervous tissue. There's no nervous tissue in the heart, just modified cardiomyocytes.

@TheNotedAnatomist 7 лет назад

You are correct ... thank-you Megan.

@wholeNwon 5 лет назад

I'm not sure you're correct. There are autonomic nerves (sympathetic and parasympathetic) in the heart. At least 2 of the nuclei of CN X innervate the heart (? all 3). Afferent pain fibers? Myocardial ischemia and other phenomena cause pain.
