Excitatory neurons A and B both synapse with neuron C. Neuron A releasesa neurotransmitter, and neuron B releases the same type and amount ofneurotransmitter plus a neuromodulator that produces EPSPs in neuron C.Action potentials produced in neuron A alone can result in action potentialproduction in neuron C. Action potentials produced in neuron B alone alsocan cause action potential production in neuron C. Which results in moreaction potentials in neuron C, stimulation by only neuron A or stimulationby only neuron B? Explain.

Watch this video (http://openstaxcollege.org/l/motorpathway) to learn more about the descending motor pathway for the somatic nervous system. The autonomic connections are mentioned, which are covered in another chapter. From this brief video, only some of the descending motor pathway of the somatic nervous system is described. Which division of the pathway is described and which division is left out?
