Nasopharyngeal section

The nasopharynx is located at the junction of the back of the nasal cavity and the upper part of the throat, just in the center of the skull. The upper part of the nasopharynx is separated from the cranial cavity by a hard skull base, and there are several nerves and blood vessels around it. The nasopharynx is rich in lymphatic tissue, and the opening of the Eustachian tube (Euclidean tube) is also here. Nasopharyngeal section is helpful for diagnosis.
