ESOPHAGUS

• From the foregut, just behind the pharynx, the oesophagus develops which maintains its tubular shape throughout the life.
• The musculature in the oesophagus is comprised of smooth muscle that comes from splanchnopleurae of the foregut.
• The distribution of skeletal muscle may be from mesenchyme present in the area of bronchial arches (I – VI) and migrates to the nearby foregut wall.
