Rules of thumb
1. More moveable part moves towards the less moveable part.
2. The distal bone/part moves towards the proximal bone/part

IN GENERAL (for this class )
Origin:
Proximal attachment. (Where
the muscle starts)
Muscle contracts towards the origin◦ Less movable OR
stationary part
Insertion:
Distal attachment
More movable part

To figure Movement ask yourself…
1. What aspect/view am I looking at?
2. How many joints does it cross?
3. Where is the more movable or distal
attachment going to move?
