The axons of the neurons which innervate the aortic bodies, aortic arch, respiratory and gastrointestinal tract, synapse in the caudal part of the solitary nucleus.[citation needed]
Distribution
The neurons in the inferior ganglion of the vagus nerve innervate the taste buds on the epiglottis, the chemoreceptors of the aortic bodies and baroreceptors in the aortic arch. Most importantly, the majority of neurons in the inferior ganglion provide sensory innervation to the heart, respiratory and gastrointestinal tracts and other abdominal organs such as the urinary bladder.[citation needed]
Development
The neurons in the inferior ganglion of the vagus nerve are embryonically derived from epibranchial neurogenic placodes.[citation needed]
