What is the first step when starting LabScribe?
Load the correct setting files
What does preview mode do?
Displays signal without savin
Which button adjusts signal size automatically?
AutoScale
What does Double Display Time do?
Double time shows on screen
What tool allows measurement of time difference?
Two cursors
What does the analysis window allow?
Perform calculations on signals
A reflex is best described as
Automatic response to stimuli
Correct reflex arc order
receptor- sensory - CNS - Motor - Effector
Stretch in muscles is detected by
Muscle spindles
Which division carries signals to CNS?
Sensory (afferent)
Which division controls involuntary functions like heart rate?
Autonomic nervous system
CNS Stands for:
Central Nervous system
Which reaction is typically fastest
Auditory
Why are auditory responses faster?
Shorter neural pathway
What increases reaction time (slower)?
Fatigue / distraction
Reaction time differs because of:
Individual nervous system variation
Reaction time measures
Time from stimulus to response
Which factor most improves reaction time?
practice
Loud / clear signals produce:
faster reaction
Weak signals produce
Slower response
Predictable signals are faster because
Brain anticipates
Reaction time depends on
Hearing sensitivity
Stronger stimulus usually
Improves speed
Predictable signals reduce reaction time due to
Neural anticipation
