Oral embryology PowerPoints

Here are the PowerPoints for our Oral Embryology lectures. I did these lectures for a few years, but for the past couple years, Dr. Koutlas has been doing them – so that’s why the slides look like they came from two different people.

I’m making some minor edits to Dr. Koutlas’ PowerPoints, as I mentioned today – just changing the slide order and deleting a few things just so that I can comfortably relate the material to you. I’m posting both versions of the PowerPoints below – but please note that the exam questions will come only from the new PowerPoints (the ones we use in class). Let me know if you have any questions.

New PowerPoints (for class)

  • Embryology part 2 (pharyngeal arches)  ppt | pdf
  • Embryology part 3 (head, face, oral cavity)  ppt | pdf

Old PowerPoints (optional reading; not required)

  • Embryology part 1  ppt | pdf
  • Embryology part 2  ppt | pdf

Diagram of what happens to female germ cells

Here’s an interactive drawing I made that shows what happens to female germ cells over time. I think it’s kind of helpful to see the numbers (and stages) of the germ cells mapped out by age – it gives you a visual sense of what happens throughout life.

I can’t post the drawing on our website because of wordpress limitations – but I was able to post it on my Pathology Student website. Yay!

Respiratory tree drawings

Thought I’d share a drawing with you guys in case it helps. It’s a better version of the one I made in class showing how the wall of the respiratory passageways changes as you go from bronchi to alveoli. There are three versions, so you can use it fully labeled, partially labeled, or unlabeled, however it suits you best. Let me know if you find it useful – if so, I’ll make more 🙂


Labeled with passageways only:

Fully labeled:



Quick video on stomach vs. small intestine

When we talked about the GI tract, I mentioned that when I was first learning this stuff as a student, I got hung up on trying to tell apart stomach and small intestine. They both have glands at the bottom and other structures (pits in the stomach, villi in the small intestine) on top…and I had a hard time visualizing how they were different.

So I made a short video explaining the difference. I think it’s easier to understand if you can see someone drawing on the pictures. So here it is – I hope if some of you had the same problem that this will solve it!
