Title: Final Exam, 8-9 Lecture


1
Final Exam, 8-9 Lecture
  • BUR 106, Tuesday, May 13, 9 am-12 noon

2
Final Exam, 9-10 Lecture
  • ART 1.102, Friday, May 9, 2-5 pm

3
Final Exam, 2-3 Lecture
  • BUR 106, Monday, May 12, 9 am-12 noon

4
Two major types of muscle
  • Smooth
  • Striated a. skeletal
  • b. cardiac

5
My knowledge about striated muscle
  • I know the structure A, I bands, Z lines
  • I know the sliding filament hypothesis, the
    cycling of actin and myosin
  • I know how muscle relaxes
  • I understand how muscle contractions are
    controlled by nerves (motor units)
  • I know what twitch and tetanus mean

6
I know
  1. All of this
  2. Most of this
  3. Some of this
  4. None of this

7
Set-up for the experiment
8
How does a muscle fiber contract?How does the
nerve command the contraction?How does a
muscle fiber relax?How is smooth, graded force
generated in a muscle?

15
What is the switch for muscle fiber contraction?
  1. ATP
  2. Myosin
  3. Actin
  4. Ca

16

17
Why does skeletal muscle relax?
  1. the action potential is over and the muscle
    fiber returns to its resting membrane potential
  2. Ca is sequestered into the SR
  3. muscle runs out of ATP
  4. an inhibitory neurotransmitter is released that
    causes the muscle to relax.
