Ratios

The human body is a thing of beauty.  There are very complex functions that happen everyday without even the most knowledgeable doctors being aware.  We cannot hope to fully realize those ideas in my class today but we can begin to see some of the relationships present on the surface.  We will be looking at the ratio of the Femur (thigh bone) to the overall height of the person.  The lab can be found here.  We will also be looking at how the bicep and the triceps work to control arm movement.  The model for muscular motion can be found here.  The lab write up for the model can be found here.
The start up for today is "what is the technical name for finger bones?"
