10 tips for studying the skeleton

One of the first major challenges in learning A&P is learning all the bones and bone features of the human skeleton.  Many students have not had much experience in memorizing physical structures to be identified by sight.

This video from my friend Paul Krieger is a good place to start.  It summarizes some of the basic shortcuts and tips that will help you learn the human skeleton . . . tips that will help you learn any anatomical structures of the human body.

Here are some additional links related to Professor Krieger's "10 tips"

Here's another resource from Professor Krieger that my own students find to be very helpful in learning the human skeleton as well as other concepts of A&P

Protein folding game

A&P students should be aware of the basic elements of protein folding:

Your textbook describes how the primary structure (a sequence of amino acids determined by the genetic code) is folded into a twisted and pleated secondary structure, then folded again into a complex tertiary structure.  Sometimes, tertiary proteins are combined to form quaternary proteins.  Sort of like origami, but way more useful. And way tinier.

I'd like to mention a interesting phenomenon related to protein folding and "citizen science" using an online game called Foldit.  

The Foldit game is an online puzzle game in which anybody can try their hand and finding which way a given protein folds most efficiently.  Interestingly, this has proven to yield useful results for biochemists not obtainable by traditional methods.

If you like video games . . . and the idea of actually contributing to scientific knowledge intrigues you . . . why not try your hand at Foldit?
