A 2-year-old toddler presents to clinic with his parents. The patient’s mother complains that the child has excessive salivation and occasionally drools due to his increased saliva. The toddler was born at full-term without complication and is otherwise healthy. Ear, nose, and throat exam reveals excessive salivary pooling in the mouth. Osteopathic structural examination would most likely reveal TART changes at what levels given this patient’s presentation?
