[1] These all emerge from pathways in the medulla oblongata. [1] A lower motor neuron lesion can impair their function. [5] [1]

There is disagreement over the definitions and criteria used to delineate various disorders and whether some of these conditions should be classified as ...
Nucleus ambiguus - (which affects vagus nerve and glossopharyngeal nerve) - localizing lesion (all other deficits are present in lateral pontine syndrome as well) Ipsilateral laryngeal, pharyngeal, and palatal hemiparalysis: dysphagia, hoarseness, absent gag reflex (efferent limb—CN X) Descending sympathetic fibers
