3. The drug atropine inhibits parasympathetic activity. Predict why an ophthalmologist would use this drug when examining the interior of a patient's eye. (E1) 4. In an experiment using an isolated motor neuron, researchers observed that a minimum level of stimulation was needed to initiate a response. If a stronger stimulus was applied, there was no increase in the magnitude of the response or the speed of the response. Regardless of the stimuli, amplitude and duration of the action potential were the same. What principle do these observations demonstrate? What does this principle depend on? (E3)
