Recent advances in endoscopic procedures have enabled more thorough observation of the pharynx. For observation of pharyngeal lesions, endoscopists need a good knowledge of pharyngeal anatomy. In this paper, we demonstrate the anatomy and histology of the pharynx, as well as the endoscopic view of the normal pharynx. The pharynx is that part of the digestive tube, which is located behind the nasal cavity, the mouth and the larynx. The pharynx is limited by the posterior part of the sphenoid bone body and the basilar part of the occipital bone(above). It is continuous with the esophagus(below)and is separated by loose areolar tissue from the cervical portion of the vertebral column(behind)and opens into the nasal cavity, the mouth and the larynx(in front). Histologically, the pharyngeal wall has three coats : the mucosa, the proper muscles and the adventitia.
