Anatomy & Physiology

Course Description

This course is a meticulous overview of upper aerodigestive tract anatomy and physiology.  It serves as a foundation for professionals addressing the needs of patients with voice and swallowing problems and is especially critical when preparing for transnasal and transoral endoscopy competency. It provides description of the complex interactions of the nasopharynx, pharynx and larynx.  Muscle origins, functions, nerve innervations and vasculature structures are detailed in context of models and actual endoscopic images.
