  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

  3. 1 Twizzler strand = myofibril Twizzleranalogy 1

  4. 1 bundle of twizzlers = fascicle Twizzleranalogy 2

  5. 1 package of Twizzlers = Muscle belly The packaging = tendon Twizzler analogy 3

  6. Büech’sTwizzlerAnalogy LABw/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 epimysiumsurrounding the muscle belly • Extra Press & Seal at the ends represents the tendon that attaches muscle to bone

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

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

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

  10. Synergist- muscle that assists the prime mover

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

  12. Anterior shoulder and arm

  13. Anterior forearm

  14. Anterior thigh

  15. Lateral thigh

  16. Posterior thigh
