In the Power Point today we completed our discussion about energy and muscle contraction and related the concept to everyday topics such as different forms of exercise, like those that have varying degrees of aerobic and strength building qualities. We also went on to begin the discussion about specific points that muscles attach to bones (origin and insertion) and the various ways that skeletal muscles move joints, such as flexion and extension.
The lab portion was devoted to reviewing all of the dissected cat muscles in preparation for the pin test tomorrow.
