Mnemonic Monday: Structures of the Diaphragm

0

By Haley Masterson

Mnemonics are an important tool for approaching Gross Anatomy. Here’s one for the diaphragm that will help you not only in orienting yourself in the lab, but also in identifying cross-sectional levels on x-rays in the future.

I Ate 10 Eggs At 12

The diaphragm has 3 main hiatuses – the hiatus of the inferior vena cava (IVC), the esophageal hiatus, and the aortic hiatus. The IVC passes through the diaphragm at the level of T8 (I “ate”), the esophagus passes at the level of T10 (“10 Eggs”), and the aorta passes through at the level of T12.

 

Annotation Nation

By Tim Durso

Annotation NationOne of the greatest challenges in studying for Step 1 is deciding what information is worth trying to remember. In an ideal world, you’d be able to memorize every bit of information you come across the first two years of med school, but if you could do that you’d be playing blackjack in Las Vegas with Tom Cruise instead of cramming your brain full of lysosomal storage diseases (that’s a Rain Man reference for those less movie-inclined). One of the best ways to machete your way through the thicket of medical knowledge out there is to annotate your handy-dandy version of First Aid (see here for the latest and greatest version).

While everyone agrees that annotation is an essential part of the sacred rite that is Step 1 studying, everyone seems to have a different approach. I’m going to try to help analyze some of these different approaches, and hopefully you’ll come away with a better understanding of what might work for you in your preparation. To accomplish this, I’m going to borrow elements from the famous children’s tale of “Goldilocks and the Three Bears.” If you haven’t heard of this story, call your parents and ask them why, and then Google it before reading further.

Mnemonic Monday: Hypersensitivity Reactions

1

By Haley Masterson

The 4 categories of hypersensitivity reactions is one of those subjects many students suspect we’ll never need to remember. But, in fact, this topic will likely haunt us for the rest of our medical career no matter what field we go into (even surgical residents have to review this topic for their ABSITE exam), so you may as well memorize the 4 categories now.

USMLE Exams: What is a good score?

4

By Edison Cano

A commonly asked question among US graduates and International Medical Graduates (IMGs) is what is a good score on the USMLE exams? While we all agree that higher scores are better, there are wildly differing opinions amongst friends, classmates, and various internet resources.

This question becomes harder to answer because we all come from different backgrounds and with different expectations, but as we all have different plans, time, and responsibilities, we need to tailor our work based on our own goals. (more…)
