Presentation Transcript

  1. What have we been learning?? • Types of Muscle • Muscle Structure • Muscle Stimulation

  2. Types of Muscle

  3. What are the 3 types of muscle?

  4. Muscle Structure

  5. Put these in order from outer to inner • Connective Tissue • Perimysium • Fascia • Epimysium • Endomysium • Muscle Groups • Fascicles • Muscle Fibers • Myofilaments • Myofibrils CHECK WITH A PARTNER

  6. Muscle Structure What is this?

  7. Let’s look inside a myofibril

  8. Inside a Myofibril

  9. Muscle Stimulation

  10. What’s the difference between motor unit & neuromuscular junction? • Motor Unit: one neuron & the muscle fibers it controls • Neuromuscular Junction: one neuron and one muscle fiber.

  11. Let’s Label the Neuromuscular Junction CHECK WITH A PARTNER

  12. Can a neuron contain muscle fibers?? • What are the circle like structures in the neuron? • What is the muscle fiber in this picture?

  13. Muscle Stimulation Process Ca++ • Impulse travels down neuron • Once an impulse travels down the neuron, where does Calcium (Ca++) enter the neuron? • What does the Calcium do?

  14. Muscle Stimulation Process 3. The neurotransmitters released from the vesicles do what? • Attach to muscle fiber receptors

  15. Muscle Stimulation Process 4. What is entering the muscle fiber? • Sodium (Na+)

  16. Muscle Stimulation Process 5. What happens to the neurotransmitters after sodium enters the muscle cell? - Travel back into vesicles

  17. Muscle Stimulation Process 6. Muscle Impulse travels INSIDE muscle fiber to myofibril. 7. What is released from Sarcoplasmic Reticulum (SR)? Calcium

  18. Muscle Stimulation Process: Sliding Filament Theory 1. Ca++ released from SR attaches to what myofilament? - actin

  19. Muscle Stimulation Process: Sliding Filament Theory 2. Myosin heads attach to actin at binding sites

  20. Muscle Stimulation Process: Sliding Filament Theory 3. Myosin pushes actin back (Walk along actin)
