What role does the motor neuron play in stimulation of muscle
contraction?
What role does the sarcoplasmic reticulum play in muscle
contraction?
What is the difference between aerobic and anerobic muscle
contraction?
What happens in a reflex response?
As the resistance (load) to muscle contraction increased, what
happened to the velocity of muscle contraction?
a) it increased
b) it stays the same
c) it increased dramatically and then leveled off
d) it decreased
2) how is wave summation achieved in vivo (that is, in the
living muscle)?
a) by decreasing the amount of potassium
b) by increasing the strength of a neuron’s action potential
c) by increasing the frequency of neuron firing
d) by myelinated great the neuron
1. What role does a play in the actual contraction of a muscle ber (skeletal and cardiac)? 2. How do cardiac muscle and skeletal muscle differ in the role of Cain stimulation of muscle fibers? How does this difference affect the changes in membrane potential in cardiac muscle? 3. Based on the information in questions 1 and 2 explain why cardiac muscle does not demonstrate tetanic muscle contractions
