Question

Quizplus · Accepted Answer

The bulbar muscles are enervated by the motor neurons emanating from the brainstem. This muscle group controls the epiglottis and other glottic structures, tongue, mouth, larynx, and throat. Bulbar muscle weakness impairs swallowing, coughing, speech, and other throat and pharyngeal activities. Bulbar muscle weakness also leads to severe fixed and variable extrathoracic upper airway obstruction on forced inspiratory and expiratory respiratory efforts.
