For many years, I've been producing online lecture presentations as previews and supplements to the classroom experience in my A&P courses. Sometimes, I use these to keep "teaching" while away at a conference or meeting.
In 2006, long before "flipping" became a common phrase among professors, I decided to make my classroom more interactive by putting some of the "you don't really need me in person for this" material online for preview before coming to class. I wasn't creative enough to call it something catchy and cool like flipping, but simply it "Preview Presentations." For each module in the course, students were required to watch these before coming to class for discussion, questions, and additional lecture presentations on the "hard to understand" concepts that require some back-and-forth between me and my students.
I summarized my case of putting interactive, narrated PowerPoints that include built-in self-testing quizzes in an online presentation on our companion website The A&P Professor. That was a version of a well-received workshop I presented at a regional HAPS conference in Macon GA a few years ago.
Recently, I re-created my presentation to focus on the latest generation of software plugin that allows for video or audio narration and more types of interactivity in quizzes.
Rather than summarize my experience here and suggest ways that you might consider adapting some of it to your A&P course, I'll just give you the link to my presentation (using said technology) that includes a summary handout that you can print out:
