Esophagus 3D

  • Description                                                                            
    • * Is an approximately 25 cm narrow muscular tube that begins in the neck at the lower border of the cricoid cartilage, where it is continuous with the lower end of the pharynx.
    • * Descends in front of the vertebral column through the superior and posterior parts of the mediastinum, and pierces the diaphragm at the level of tenth thoracic vertebra.
    • * Ends by opening into the stomach at its cardiac end at the level of eleventh thoracic vertebra.
    • * Has three constrictions. Upper constriction at the beginning of the esophagus at the level of the cricoid cartilage (C6) is caused by the cricopharyngeus muscle, middle constriction by the aortic arch and then left main bronchus, and inferior constriction at the esophageal hiatus of the diaphragm (T10).
    • * Receives blood from the inferior thyroid, bronchial, esophageal, left gastric, and left inferior phrenic arteries.
