The monosynaptic reflex is mediated by muscle spindles, and produces an inhibitory response. True or false.
false - produces excitatory on agonist
Which of the following is not a basic component of spinal reflexes?
Motor neuron
Sensory afferent
,
Somatosensory cortex
somatosensory cortex
Electrical Vestibular Stimulation (EVS) uses small electrical currents to activate _________.
vestibular afferents
Which of the following properties does not describe Renshaw Cells?
Renshaw cells act as a “limiter,” preventing overactivity of the effector muscle
Renshaw cells are activated collaterally from Alpha motor neuron
Renshaw cells release GABA as an inhibitory neurotransmitter.
As motor neuronal activity increases, Renshaw Cells activity increases
Renshaw cells release GABA - nO they release glycine
autogenic excitation involves ___ of ____
Autogenic inhibition involves ___ of ____
Recipricol excitaion involces ___ of ____
reicpricol inhibition involves ____ of _____
autogenic excitaiton is faciliation of the agonist muscle
reciprocal inhibition is an inhibition of the antagonist
autogenic inhibition is inhibition of the agonist
recipricol excitation is excitation of the antagonist
While Tyler is Home Alone, dog burglars try to steal Winston. One of the burglars sneaks through the basement and steps on a nail to cause pain on the bottom of her foot. What specific pathway does pain travel through to get to the cortex?
spinothalmic
Which of the following is not a function of pre-synaptic inhibition?
Prevents calcium channels opening due to GABA release onto the pre-synaptic neuron
Decreases the amount of neurotransmitter released onto the pre-synaptic neuron
Decreases the amount of calcium coming into the pre-synaptic neuron
Neurotransmitter release is decreased onto the post-synaptic neuron
decrease the amount of NT released onto the pre-synaptic neuron
pre-synpatic inhibition acts a limiter to prevent the overactivity of. a muscle
false - that is recurrent inhibition
Which of the following does not describe autogenic inhibition?
Inhibits the agonist muscle
Comprises of an inhibitory interneuro
Ib inhibitory neuron synapses directly onto the motor neuron
Ib inhib.. (its 1a) stretch reflex

Correct answer:
True
False
true.
