This Muscular System section from the Human Body Systems book includes: Structure of Skeletal Muscle, Cardiac Muscle, and Smooth Muscle, How Muscle Contractions Occur, Myofibril (actin, myosin) Interactions, Types of Contractions, Agonist and Antagonist muscles, Origin and Insertion of Muscle.
***You can buy all of the body systems together in the Human Body Systems book!***
All of these subjects are taught using clear and informative hand drawn and written pictures and text. These can be used as graphic notes given to students (projected on board) or as individual or group work.
I have included BOTH the color and black and white versions so that you can use them in a variety of ways. Having students color-code the black and white versions have helped immensely in my classes!
