Heart Burn
  1. Phases of swallowing
    1. Oral phase
      1. Voluntary
        1. Initiated by tongue forces a bolus of food back toward the pharynx
          1. Activation initiates involuntary swallowing reflex in the medulla
          2. Pharyngeal phase
            1. Reflexive
              1. Soft palate pulled upward,
                1. Epiglottis moves to cover the opening to the larynx;
                  1. Larynx moves upward against the epiglottis
                    1. Upper esophageal sphincter relaxes
                      1. Peristaltic wave of contraction initiated in pharynx
              2. Esophageal phase
                1. Controlled by swallowing reflex and enteric nervous system
                  1. Primary peristaltic wave: Swallowing reflex travels down the esophagus
                    1. Secondary peristaltic wave: Food not cleared initiates; mediated by the enteric nervous system; begins at the site of distention
                2. Causes of dysphagia
                  1. Oropharyngeal dysphagia
                    1. Neurological disease
