Oesophagus. Coloured scanning electron micrograph (SEM) of a freeze-fracture through the muscularis externa of the oesophagus. This forms part of the muscularis mucosa found throughout the gut. The upper part of the oesophagus contains striated muscle,which is muscle tissue characterised by strips. This muscle layer allows independent movements within the width of the mucous membrane. The oesophagus is a muscular tube about 25 centimetres long that runs from the back of the throat to the stomach. Magnification not known | |
