Derived from precursor cells adjacent to somites 1
Derived from precursor cells adjacent to somites 1-7, this structure upregulates receptors for cannabinoid and melanin concentration hormone receptors in response to low levels of cholescystokinin. In response to baroreceptor signaling from the carotid sinus, this structure induces bradycardia through a muscarinic receptor-mediated response. Damage to this structure can cause a contralateral deviation in the palatine uvula, as well as hoarseness.  A namesake reflex involving this structure involves crosstalk between its nodose ganglia and its dorsal motor nucleus. Along with the esophagus, this structure passes through the esophageal hiatus at T10. For 10 points, name this structure of the central nervous system that functions as the major source of the parasympathetic innervation in the body and is known as the tenth cranial nerve.
