It is a muscular tube approximately25 cm long extending from the pharynx to thestomach. The esophagus begins at the lowermargin of the cricoid cartilage opposite thesixth cervical vertebra and enters the gastricorifice at the level of the twelfth thoracic verte-bra.There are some morphological and...
