KNH 184 EXAM 3 2025/2026 QUESTIONS
AND ANSWERS 100% PASS
Executive - ANS sends movement instructions to effector
effector - ANS executes movement instructions
instructions sent in advance - ANS open loop characteristic
instructions executed without interuption - ANS open loop characteristic
no way to correct errors because of no feedback - ANS open loop characteristic
best used in stable environments not useful in changing environments - ANS open loop
characteristic
what are good candidates for motor programs - ANS kicking and typing- things we don't
really have to think about
what are deafferation studies - ANS removing feedback
what do afferent neurons do - ANS send nerve signals from the periphery to the spinal cord

, what do efferent neurons do - ANS send nerve signals from the spinal cord to the
peripherary
what is deafferation - ANS severing afferent neurons
proprioceptive signals from muscles can or cannot reach the central nervous system -
ANS cant
motor pathways are or are not affected - ANS are not
true or false movements must be centrally planned and directed - ANS true
some of the most compelling evidence for motor programs comes from - ANS looking at the
effects of mechanically blocking a limb
inhibiting actions basic premice - ANS if a movement cannot be stopped it might be under
the control of something like a motor program
example of an inhibiting action - ANS checked swing in baseball
example of inhibiting action experiment - ANS slater-hammel (1960) initiating a motor
program task is to lift a finger of a timer at exactly 800msec
startle response - ANS associated with faster rt, a protective response and loud noises
"supercharge" the motor program response
central pattern generator - ANS initiating stimulus provides sets of a repeating pattern of
stimulation, effect is similar to a motor program but the origin is believed to be genetically
determined
