Skeletal Muscle Phy (effect Of Stimulus Frequency On Skeletal Muscle)

Question 1

Define treppe

Answer 1

• the progressive increase in force generated when a muscle is stimulated in succession
  
  • when a muscle twitches follows one another closely, with each successive twitch peaking slightly higher than the one before

Question 2

What is wave summation?

Answer 2

-occurs when muscle fibers that are developing tension are stimulated again before the fibers have relaxed

Question 3

How is wave summation achieved

Answer 3

-by increasing stimulus frequency, or rate of stimulus delivery to the muscle

Question 4

Is maximal force achieved during a single twitch of a skeletal muscle?

Answer 4

No

Question 5

Wave summation increase the force produced in the muscle. Another way to increase the force produced by a muscle is to

Answer 5

-increase the number of activated motor units

Question 6

Does the force generated by the muscle change with each additional stimulus?

Answer 6

-As the stimulus frequency increased, the muscle tension generated by each successive stimulus also increased, and a limiting maximum value was observed
