  • Oropharyngeal motor dysphagia results from impairment of the voluntary effort required in bolus preparation or neuromuscular disorders affecting bolus preparation, initiation of the swallowing reflex, timely passage of food through the pharynx, and prevention of entry of food into the nasal and the laryngeal opening. Paralysis of the suprahyoid muscles leads to loss of opening of the UES and severe dysphagia. Because each side of the pharynx is innervated by ipsilateral nerves, a unilateral lesion of motor neurons leads to unilateral pharyngeal paralysis.

  • The brain and spinal cord compose the Central Nervous System (CNS), which is the control center of the body. Inputs from muscles, involuntary organs, and senses travel through the nerves of the Peripheral Nervous System (PNS) into the CNS where they are interpreted. Signals may travel within the brain to separate functional areas. Instructions are then sent outward again for voluntary movement and involuntary regulation to complete the endless loop of the nervous system circuitry.
