1.2 The muscular system Flashcards
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.
