CrashCourse

We continue our look at your bones and skeletal system, skipping over the silly kid's song in favor of a more detailed look at your axial and appendicular skeleton. This episode also talks about the structural and functional classifications of your joints and the major types of body movement that they facilitate.

Pssst... we made flashcards to help you review the content in this episode! Find them on the free Crash Course App!
