Nasopharynx function

Functions of the Nasopharynx In Respiration: It is the part of the pharynx involved in respiration, working with the nasal cavity, larynx and the rest of the airways during breathing Normal Function The nasopharynx is lined by pseudostratified columnar ciliated epithelium with goblet cells (Dungworth, 1993). Abundant lymphoid nodules are present in the submucosa. The eustachian tubes extend from the middle ear to the nasal cavity The nasopharynx is an air-containing cavity at the back of the nose, which occupies the uppermost extent of the aerodigestive tract. It's like a small cuboidal box about two to three centimeters front to back and about three to four centimeters top to bottom and side to side For example, the nasopharynx is made up of respiratory epithelium, a protective mucous membrane that coats the airways and respiratory tract. The nasopharynx is also where the adenoid tonsils are located, a patch of tissue high up in the throat that makes up some of your tonsils The nasopharynx functions as an airway in the respiratory system. Also contained within the nasopharynx are the adenoids, or pharyngeal tonsils. 2

The nasopharynx is at the top of the throat, or pharynx. The nasopharynx is basically the upper-most part of the human throat. It sits just behind the soft palate in the mouth and connects the nasal passages with the larger pharynx, which is the throat system as a whole Nasopharyngeal carcinoma is difficult to detect early. That's probably because the nasopharynx isn't easy to examine and symptoms of nasopharyngeal carcinoma mimic those of other, more-common conditions. Treatment for nasopharyngeal carcinoma usually involves radiation therapy, chemotherapy or a combination of the two The pharynx is divided into three regions: the nasopharynx, the oropharynx, and the laryngopharynx. The nasopharynx is flanked by the conchae of the nasal cavity, and it serves only as an airway. At the top of the nasopharynx are the pharyngeal tonsils

The Nasopharynx. Nasopharynx is the upper part of the throat (pharynx) that lies behind the nose. The nasopharynx a box-like chamber about 1½ inches on each edge. Nasopharynx lies just above the soft part of the roof of the mouth (soft palate) and just in back of the nasal passages The human pharynx is conventionally divided into three sections: the nasopharynx (epipharynx), the oropharynx (mesopharynx), and the laryngopharynx (hypopharynx). The Eustachian tubes connect the middle ear to the nasopharynx, and serve to equalize the barometric pressure in the middle ear with that of the ambient atmosphere The pharynx, consisting of the nasopharynx, oropharynx, and laryngopharynx (sometimes referred to as the hypopharynx), extends from the mouth and nasal cavities to the larynx, where it becomes continuous with the esophagus. The pharynx serves as a common passage for food, fluids, and air The nasopharynx functions as the passageway between the nasal cavity and the larynx. Air transported through this area passes very near the tonsils. The tonsils are a part of the immunologic system and are capable of activating certain defense mechanisms of the body when foreign material and infectious agents are detected

It is connected to the nose and is separated from the mouth by the soft area at the back of the roof of the mouth (called the soft palate). The base of the skull forms the top of the nasopharynx

The laryngopharynx is where both food and air pass. It can be found between the hyoid bone and the larynx and esophagus, which helps guide food and air where to go. It is a part of the pharynx. A smooth mucous membrane covers the side and back walls. At the back of the larynx, the anterior wall of the laryngopharynx exists The nasopharynx is part of an area of the body called the upper aerodigestive tract. The upper aerodigestive tract includes the nose, mouth, and throat. The nasopharynx is located where the inside of the nose (the nasal cavity) meets the back of the throat (the pharynx). The nasopharynx is covered by cells called squamous cells The two that we'll see now are the levator palati and the tensor palati. To see these muscles, we'll remove the mucosa of the nasopharynx. Here's the end of the cartilage of the auditory tube. Here below it is the levator palati muscle: its full name is the levator veli palatini Human respiratory system - Human respiratory system - The pharynx: For the anatomical description, the pharynx can be divided into three floors. The upper floor, the nasopharynx, is primarily a passageway for air and secretions from the nose to the oral pharynx.
