 Multipennate steadying the joints
- Fibers are running in several directions - E.g. Deltoid
- Tendon branches within muscle  Antagonist
- E.g. Deltoid - Muscles that inhibits / prevents the
movement to help produce a smoother
primary action
- E.g. Quadriceps: prime mover
Hamstring: antagonist
 Fixators
- Contracts isometrically (produce an
increase in muscle tone but no
movement)
- E.g. Shoulder girdle muscles
