You stimulated the frog gastrocnemius muscle with varying voltages. Increasing the stimulus voltage caused the force of contraction to:

You stimulate a sensory receptor at different intensities. As stimulus intensity increases, receptor potential amplitude:

In the EMG lab, you measured the amplitude of the EMG tracing while the wrist was flexing.  The amplitude of the tracing while holding a heavy weight is _____ than the tracing when no weight was held. 

When a subject is NOT mentally active, the synchronicity of EEG waves:

You added three solutions to glycerinated muscle to observe muscle contraction.  Which of the three solutions caused the strongest muscle contraction?

In addition to the GSR, what TWO physiological variables were measured by the Biopac device?

What specific nervous system is responsible for the GSR?

What is Phantom Limb Syndrome?

An EMG measures:

Explain the reason for this difference in amplitude.
