The video tutorial explains the identification of a pre-ganglionic parasympathetic neuron originating from the brain stem and a post-ganglionic sympathetic neuron associated with norepinephrine. It further describes the process of bronchodilation, where epinephrine from the adrenal medulla binds to beta 2 adrenergic receptors, causing airway dilation.
