Lab 11 Flashcards
What was the question of the muscle fatigue and motor neuron stimulation lab?
Do the motor neurons in a muscle signal the muscle more, less, or the same when the muscle becomes fatiqued?
What were we measuring in the muscle fatigue and motor neuron stimulation lab?
Voltage change between the highest force and muscle fatigue and its percent change
What was your hypothesis?
Motor neurons send less signals as muscle fatigues.
What was your prediction?
Decrease in voltage, negative percent change
What were the results?
Increase in voltage, positive percent change
Explain what happens with the motor neurons when a muscle fatigues.
When a muscle fatigues, the voltage from the motor neurons increases. This increase indicated the brains attempt to get the muscle to contract, but the muscle is unable to.
