Identify from the clue as smooth skeletal or cardiac muscle there may be more than one muscle

Identify from the clue as smooth, skeletal, or cardiac muscle. There may be more than one muscle.

  • 1. Muscle attach to the bone

  • 2. Tire quickly

  • 3. Found in stomach and blood vessels

  • 4. Not striated muscle (no bands)

  • 5. Voluntary muscle

  • 6. Involuntary muscle

  • 7. Found in heart

  • 8. React slowly

  • 9. Does not get tired

  • 10. Striated muscle (have bands)


On a sheet of paper identify as skeletal smooth or cardiac muscle

On a sheet of paper identify asskeletal, smooth, or cardiac muscle

  • Voluntary muscle

  • Involuntary muscle

  • Muscles that are control by conscious thought

  • Muscle attach to the bone

  • Found in stomach and blood vessels

  • Found in heart

  • Found in legs and arms

  • Breathing and digesting food

  • Striated muscles

  • Playing basketball

  • React quickly

  • React slowly

  • Tire quickly

  • Tire more slowly

  • Does not get tired


Muscle fatigue lab

Muscle Fatigue Lab

  • On a separate sheet of paper, write your name, period and date and title muscle fatigue lab

  • Read aloud the introduction

  • Copy the problem on your paper

  • Write your hypothesis on your paper

  • Copy the materials on your paper

  • Read aloud the procedures

  • Copy the observation table and fill it in with numbers

  • Construct 2 bar graphs (number of fists, number of arm lifts)

  • Answer in complete sentences the conclusion questions


Why do skeletal muscles get tired

Why do skeletal muscles get tired?

  • Calcium is leaking from muscle cells as calcium is necessary which weakens the muscles.

  • Less oxygenated blood (bleeding, tight clothing). Oxygen is required for the muscle to work optimally.


Why does your heart never gets tired

Why does your heart never gets tired?

  • There are more mitochondria in the cardiac muscle than in any other muscle.

    Remember the function of the mitochondria is to make energy for the cell. More mitochondria means more energy and the cardiac muscle does not get tired.

  • 3 types of muscles

    • Skeletal

    • Cardiac

    • Smooth

  • How muscles work together in pairs
