1. SKELETAL MUSCLE analogy LAB

2. Terms’ Greek Roots epi = upon peri = around endo = within or inner
mys = muscle
sarco = flesh
lemma = husk
fasci = bundle

4. Twizzler analogy 1
1 Twizzler strand =
myofibril

5. Twizzler analogy 2
1 bundle of twizzlers =
fascicle

6. Twizzler analogy 3 1 package of Twizzlers = Muscle belly
The packaging =
tendon

7. Büech’s Twizzler Analogy LAB w/Plastic Wrap
Each strip of the Twizzler represents a myofibril (muscle fiber)
Wrapped in Plastic Wrap endomysium
Several myofibrils wrapped together in Plastic Wrap form perimysium representing a fascicle
Several fascicles are wrapped in Press & Seal wrap to represent the epimysium surrounding the muscle belly
Extra Press & Seal at the ends represents the tendon that attaches muscle to bone

8. Origin- The location where the muscle is attached to the relatively immovable end of the bone

9. Insertion- end of the muscle that is attached to the movable bone

10. Prime mover- the muscle that provides most of the movement

11. Synergist- muscle that assists the prime mover

12. Antagonist- the muscle that opposes the action of the prime mover

14. Anterior forearm

15. Anterior thigh
