There are two nuclei in the regulatory center for the cardiac (heart) system: the cardioacceleratory center and the cardioinhibitory center . These are vital reflexes for maintaining heart rate. The action potentials generated have differing effects on heart rate. Given this information, answer the following questions:
Where in the brain would you find the cardiac centers? (give one of the four major regions)
What part of a neuron would be in a center? In which autonomic division are pathways descending from the cardioacceleratory center?
In which autonomic division are pathways descending from the cardioinhibitory center?
Which center is part of a pathway that contains only cholinergic neurons?
Which center is part of a pathway that contains a cholinergic and adrenergic neuron?
Which center would be part of a neuron pathway that would have cell bodies in the lateral horn of the spinal cord and a synapse in the sympathetic trunk ganglion?
From which center would action potentials travel through a cranial nerve? Which cranial nerve number?
