1.2.2 Distinguish between the different types of muscle
1.2.1 What are the characteristics of Muscle?
1.2.4 Define the terms origin and insertion of muscles.
• The origin is where the tendon of the muscle joins the stationary bone(s). Usually more proximal. • The insertion is where the tendon of the muscle joins the moving bone(s). Usually more distal.
1.2.3 Annotate the structure of skeletal muscle.
