SY305C Pathological Model of Oropharynx
The pharynx of human body is divided into nasopharynx, oropharynx and hypopharynx. Nasopharynx is between skull base and soft palate plane.
And is communicated with the nasal cavity forward through the nasal posterior hole.
On both sides of nasopharynx, eustachian tube pharynx is communicated with middle ear and tympanum. Posterior pharyngeal recess is the most common site of nasopharyngeal ai.
The oropharynx is located between the soft palate and the superior margin of the epiglottis, and communicates with the oral cavity forward through the pharyngeal isthmus.
The out sidewall receives that palatine tonsil.
The hypopharynx is located between the upper margin of epiglottis and the plane of the lower margin of the 6th cervical vertebra, and communicates with the laryngeal cavity through the laryngeal orifice forwards and passes through the esophagus downwards.
The piriform recess on both sides of the laryngeal orifice is the place where the foreign body is easily retained.
And is communicated with the nasal cavity forward through the nasal posterior hole.
