Hey everyone!

First, thank you to everyone who responded to my slightly-exasperated email last week. I appreciate all the encouragement, and it's nice to be reminded that we all have struggles and that we're all doing our best. Thanks for helping me not feel so alone :)

A little different for this week's email. I have three updates/new things to share.

A&P 2 Course Enrollment - Re-opening next week! 🫀

My top priority recently has been creating videos and resources for my A&P 2 course that started last month. The course already includes 23 exclusive videos and counting.

It's been a huge undertaking, stressful at times, but also super rewarding to be creating something that really helps people achieve their goals.

In fact, I've already heard from several students in my course who have improved their A&P 2 test scores. Here's a message I got last night from a student in the course:

If you missed the first enrollment window and want to improve your scores in A&P 2 as well, there will be another chance to join next week. I'll send an email out next Monday (9/28/26) about it, but you can also go to the easy-to-remember URL courses.siebertscience.com anytime next week to join and learn more about it :)

New YouTube Video + Free Guide: Muscles of the Shoulder & Upper Arm 💪🏼

I finished a new YouTube video last week, and it went live this morning! Pretty excited about this one.

If you've struggled with learning origins, insertions, and actions of muscle groups, then this video will be really helpful for you.

​

• ​Anatomage provided 3D cadaveric images for the video, and the clips they gave me show each muscle fading away to reveal the origins and insertions, which made a bunch of these way easier to visualize. I'm thankful to get to work with a sponsor that actually makes my videos better, rather than just being an ad. Love their stuff!
• I focused on not just teaching the muscles, but also providing a framework for how to learn them well: (1) picture the muscle -> (2) identify the origins and insertions from your mental picture -> (3) logically think through what action the muscle would do based on the origins/insertions. Muscles are much easier to learn with this process, and if you want to see my process of learning new muscles, you might also like my "How to Learn Muscles" video here.
• Hopefully if the video performs well, it'll be the beginning of a series of muscle region videos!

New System Guide: Respiratory System 🫁

We actually finished this guide a few weeks ago, but I'm just now getting around to including it in an email. Danielle Carlson, who does most of the work on these guides, did an amazing job on this one. She's really good at getting students to think conceptually and really understand what's going on with the science.

And the (surprisingly complex) respiratory system has a lot of background info students need to know, like all the gas laws, and this guide does a great job building that background knowledge so all the respiration topics make sense. Check it out here!​

We only have one system left for these guides (Cardiovasculary)...and it's a big one, haha! Creating these has been a multiyear project, so it's exciting to see the finish line approaching :)

Have a great week, everyone!
