Axial Versus Appendicular Skeleton: Key Differences and Functions

Dr. Alsup introduces the basic categories of the human skeleton: the axial and appendicular skeletons. The axial skeleton includes bones around the body's longitudinal axis, such as the skull, neck, vertebral column, and thoracic cage. The appendicular skeleton comprises bones of the limbs and girdles, connecting to the axial skeleton. The video emphasizes understanding the location and types of bones in each category, rather than memorizing numbers. A brief review reinforces that the skull is part of the axial skeleton.
