Anatomy of the esophagus

  • Approximately 45% of the total length of the esophagus is within the neck, with the rest situated within the thorax.
  • The esophagus is innervated by the vagus nerve.
  • The esophagus has four layers:
    • Tunica adventitia (fibrous outer layer) – replaced by tunica serosa in the mediastinum.
    • Tunica muscularis (striated and smooth muscle).
    • Tela submucosa.
    • Tunica mucosa.
