Adenoids , also called Pharyngeal Tonsils , a mass of lymphatic tissue, similar to the palatine tonsils, that is attached to the back wall of the nasal pharynx i. An individual fold of such nasopharyngeal lymphatic tissue is called an adenoid. The surface layer of the adenoids consists of ciliated epithelial cells covered by a thin film of mucus. The cilia , which are microscopic hairlike projections from the surface cells, move constantly in a wavelike manner and propel the blanket of mucus down to the pharynx proper. From that point the mucus is caught by the swallowing action of the pharyngeal throat muscles and is sent down to the stomach. The adenoids also contain glands that secrete mucus to replenish the surface film. The function of the adenoids is protective.
The word throat is used for the parts of the neck anterior to the vertebral column, especially the pharynx and the larynx. The pharynx is the part of the digestive system situated posterior to the nasal and oral cavities and posterior to the larynx. It is therefore divisible into nasal, oral, and laryngeal parts: the 1 nasopharynx, 2 oropharynx, and 3 laryngopharynx. The pharynx extends from the base of the skull down to the inferior border of the cricoid cartilage around the C6 vertebral level , where it becomes continuous with the esophagus. Its superior aspect is related to the sphenoid and occipital bones and the posterior aspect to the prevertebral fascia and muscles as well as the upper six cervical vertebrae. The pharynx figs.
The three main sections of the pharynx : This figure illustrates the three main subdivisions of the pharynx. The human pharynx plural: pharynges is the part of the throat situated immediately posterior to the mouth and nasal cavity, and superior to the esophagus and larynx. The human pharynx is divided into three sections: the nasopharynx epipharynx , the oropharynx mesopharynx , and the laryngopharynx hypopharynx , which are all innervated by the pharyngeal plexus. The pharynx is part of both the digestive system and the respiratory system. As a component of the upper respiratory tract, the pharynx is part of the conducting zone for air into the lungs. Therefore, one of its primary functions is to warm and humidify air before it reaches the lungs.
The nasopharynx is, by definition, the upper part of the throat behind the nose. It is a part of the pharynx, which comprises three separate segments: the nasopharynx, oropharynx, and the hypopharynx. The nasopharynx is 2 to 3 cm wide and 3 to 4 cm long and situated behind the nasal fossa inside the occipital bone. The nasopharynx is the space above the soft palate at the back of the nose and connects the nose to the mouth, which allows a person to breathe through the nose. The soft palate separates the nasopharynx from the oropharynx, which sits just below the soft palate. The nasopharynx remains open even when surrounding muscles flex so that the person can continue to carry on respiratory functions. The nasopharynx is surrounded by the salpingopharyngeal fold and tubal tonsils, which can become inflamed when infected.

It is located behind the nose and mouth and connects the mouth oral cavity and nose to the breathing passages trachea [windpipe] and lungs and the esophagus eating tube. The throat also helps in forming speech. The throat contains the:. Throat Anatomy and Physiology.

The adenoid , also known as a pharyngeal tonsil or nasopharyngeal tonsil , is the superior -most of the tonsils. It is a mass of lymphatic tissue located behind the nasal cavity, in the roof of the nasopharynx , where the nose blends into the throat. In children , it normally forms a soft mound in the roof and back wall of the nasopharynx, just above and behind the uvula. The term adenoid is also used to represent adenoid hypertrophy. The adenoid is a mass of lymphatic tissue located behind the nasal cavity, in the roof of the nasopharynx , where the nose blends into the throat.
