Having trouble with the PEX exercises

Post the questions and we'll help

Here is the rest of it

Treppe is the phenomenon that results in _______.  maximal force production by a skeletal muscle 
 a progressive increase in the force generated with repetitive stimulation 
 an increase in the stimulation frequency 
 motor unit recruitment 

 
When the frequency of stimulation of a muscle is great enough, _______.  wave summation results 
 full relaxation of the muscle occurs 
 muscle twitches overlap 
 full relaxation of the muscle occurs and wave summation results 
 wave summation results and muscle twitches overlap. 

When wave summation occurs, _______.
When wave summation occurs, _______. 
individual muscle twitches are separated 
 the muscle fiber has received a single stimulus event 
 the muscle force generated increases 
 the muscle force generated decreases 


Why does wave summation occur? 
A large amount of time elapses between stimulations. 
 Muscle twitches are not yet overlapping. 
 Muscle fibers have been allowed to fully relax. 
 Muscle fibers are partially contracted when the next stimulus arrives

Which of the following would result in fused or unfused tetanus?
Which of the following would result in fused or unfused tetanus?  decreasing the stimulus frequency or increasing the stimulus frequency 
 decreasing the stimulus frequency 
 threshold stimulus and single stimuli 
 increasing the stimulus frequency 

Part B To transition from unfused tetanus to fused tetanus, _______.
To transition from unfused tetanus to fused tetanus, _______. 
stimulus frequency increased 
 the muscle fibers were allowed to relax 
 wave summation was not allowed 
 stimulus frequency decreased 

Part C 
Which of the following describes the relationship between stimulus frequency and muscle tension? 
When stimulus frequency increases, muscle tension decreases. 
 When stimulus frequency decreases, muscle tension increases indefinitely. 
 When stimulus frequency increases, muscle tension increases to a maximum value. 
 When stimulus frequency increases, muscle tension increases indefinitely. 

Part D
At what stimulus frequency was maximal tetanic tension developed?  140 stimuli/sec 
 130 stimuli/sec 
 50 stimuli/sec 
 146 stimuli/sec 

i have the same questions, did u find the answers?
