Document Summary
Monosynaptic reflex arc (m1) stereotyped, involuntary long loop multisynaptic reflex (m2) reflexive control of movement: stereotyped, involuntary, very fast the mi response (monosynaptic stretch reflex or gamma reflex loop) Emg activity 30-50 ms after load (way faster than typical closed-loop response) result of stretched muscle spindles spindles transmit information to spinal cord regarding environmental change (load adjustment/perturbation (change in position or force in muscle)) and synapse is made. M2 response (multisynaptic; interneurons) occurs 80 ms after perturbation **shorter than voluntary movement** - determines that it"s a reflex. Chapter 5: open-loop control and motor programs open loop control the basic open loop system consists of two parts: an executive and an effector. Without feedback, the open loop system is not sensitive to whether the actions generated in the environment were effective in meeting the goal (no stopping) *we use both these loop systems in our every day life and they operate together evidence of mps reaction time.
