What is posterior nasopharynx?

What is posterior nasopharynx?

The nasopharynx is located posterior to the nasal cavity which is lined by pseudostratified columnar epithelium. It communicates with the nasal cavities through the nasal choanae and with the middle ear through the eustachian tube. It also contains the pharyngeal tonsils (adenoids) in its posterior wall.

What is a normal nasopharynx?

Normal Anatomy The nasopharynx is a fibromuscular sling suspended from the skull base. The pharyngobasilar fascia, a tough aponeurosis, is the cranial extension of the superior constrictor muscle from the level of the soft palate to the base of the skull.

Is the Salpingopharyngeal fold in the nasopharynx?

The small tubal tonsils are located in the side wall of the nasopharynx at the orifice of the pharyngotympanic tube. The pharyngeal recess is a deep cleft behind the orifice of the pharyngotympanic tube and the salpingopharyngeal fold.

What drains into the nasopharynx?

Lymphatic drainage in the nasopharynx occurs laterally and medially: lateral drainage pathway: lymph vessels traverse the superior constrictor muscle and drain into the lateral retropharyngeal, deep cervical and posterior triangle lymph nodes.

What is nasopharynx and its function?

Can be found in the nasopharynx?

The nasopharynx represents the most superior portion of the pharynx, bounded superiorly by the skull base and inferiorly by the soft palate. The nasopharynx connects the nasal cavity to the oropharynx and contains the Eustachian tube openings and adenoids.

Is nasopharynx a tissue?

How is the nasopharynx related to the middle ear?

Anteriorly, the nasopharynx is in direct continuity with the nasal cavity through the choanae laterally in direct communication with the middle ear cavity through the eustachian tubes and inferiorly it communicates with the oropharynx along the posterior border of the soft palate.
