Consider three alpha-motor neurons of different sizes: small, medium and large. All three neurons receive input from the same
excitatory interneuron. When the interneuron fires action potentials at low frequency, only one alpha motor neuron fires action
potentials. As the action potential frequency of the interneuron increases, two alpha-motor neurons are recruited, and at
maximum frequency, all three are recruited. In what order would the three alpha-motor neurons have been recruited?
Large first, then medium, then small.
Small first, then medium, then large.
Medium first, then small, then large.
Medium first, then large, then small.
Taylor accidentally dips his fingers into a cup filled with steaming hot coffee. He immediately withdraws his hand and then exclaims “ouch!”What is the correct order of the nervous system structures involved in the scenario described above?
Select one:
a. sensory neuron, effector, motor neuron, interneuron
b. motor neuron, receptor, sensory neuron, effector
c. receptor, sensory neuron, interneuron, motor neuron
d. sensory neuron, interneuron, effector, motor neuron
Match the description with the statement that best describes the following neural circuits.
a single post-synaptic neuron receives input from multiple pre-
synaptic neurons
causes the stimulation of the post-synaptic neuron continually
similar to a positive feedback response
A. diverging circuits
B. converging circuits
C. reverberating circuits
causes a longer lasting stimulus of the post-synaptic neuron
D. parallel after discharge circuits
a single pre-synaptic neuron synapses with multiple post-synaptic
neurons
Moving to another question will save this response.
