About pharynx
found in the human body
Pharynx is a muscular tube, a length of about 12 cm, heading down, calling seven slots: slot mouth, opened a nose hind, Two Astekeus slots, and slot throat.
Pharynx common corridor for air and food.
Pharynx located beneath the skull and behind two Almnkharan slots and touches the back of the intervertebral which serves as the basis sliding pharynx and esophagus during swallowing processes and move the neck.
Pharyngeal wall consists of a thin circular fibers longitudinally and three sphincter muscles, allowing him to carry out the function of swallowing, where she works circular muscle fiber, where open pharynx muscle to bite and then constrict it Vtdfha to fall forward toward the esophagus.
Pharyngeal wall consists of two types of fabric by function, Valjze throat - nasal - consists of mucous tissue (epithelial) Emadi fringed as in the respiratory tract, while the rest of its parts Vmbtna squamous membrane applied as in the gastrointestinal tract.
Pharynx longitudinally consists of three parts:
• Part throat - nasal: It is a solid base to roll open the front to breathe, either from the rear pharyngeal remains stiff Association, Central, which remains free breathing passage. In this section opens Fallopian Awstakeos on the side wall above the soft palate.• Part throat - oral: from the back consists of three muscles sphincter, and closes after swallowing a bit of food, either out of swallowing remains open for breathing and the front closes one third back of the San and separating it from the mouth Algndbtan front (column throat front) and separated from throat epiglottis.• Part throat - laryngeal: the back wall consists of three Aasrat growths hanging until the level of the vocal cords. And on each side of the epiglottis mucous membrane extends up the side wall of the pharynx, and this membrane is what is known herewith pharynx - Almes tongue, and separating the pharyngeal opening - oral and pharyngeal opening - laryngeal. And from the bottom Atafr p into two branches, one gastrointestinal and respiratory esophagus and second, a throat.
Knows the bottom surface of the part throat - nasal soft palate SOFT PALATE, and consists of peritonitis (membrane) Powered by muscles, cause a change in the shape and location, and is characterized by the presence of a large number of mucous glands, serological, and muscle dynamics are:- Article palate muscle- Crane palate muscle
And covers the soft palate squamous membrane applied to the oral surface and the back of the nasal surface, and includes oral sewn on some taste buds, while sewn nasal respiratory membrane covered include small mucous glands, and epithelial tissue Emadi fringed.
And the soft palate valve function, where he closes the oral part of the pharynx from the mouth during chewing so as not to be impeded breathing and separates the oral part of the nasal part of the pharynx during swallowing so as not to pass some food particles into the nose. It also plays a role in changing the sound quality during a speech, and man can not speak for not connect to the mouth, pharynx, it is not possible to output speech from the nose.
