Pharynx

Pharynx (Latin pharynx) is funnel-shaped tube with a length of 12-15 cm. Crosses in her airways and digestive system. It stretches from the base of the skull to the sixth cervical vertebra, from which it distributes to the larynx (windpipe) and esophagus (the tube that connects the pharynx to the stomach). Pharynx is reinforced by cartilage, lined with mucous membrane and its wall consists of connective tissue and striated muscles.

Pharynx consists of the following three sections

  1. nasopharynx (nasopharynx) – two holes in it orifice vents. It houses the Eustachian tube, which connects the nasopharynx to the middle ear. In it helps equalize the pressure. Nasopharynx contains lymph nodes – adenoids.
  2. middle section (oropharynx) – oral pharynx, which serves for breathing and swallowing. Enclosed by the soft palate, tongue and root-storey arches. Also here is the lymphoid tissue in the form of multi-storey (cervical), almonds, lying between the two arcs.
  3. laryngeal section (laryngopharynx) – a small part of the pharynx. It contains the epiglottis, which closes when eating food airways and prevents suffocation. This happens through an unconditional (auto) reflex.

Diseases of the pharynx

Diseases of the pharynx may be inflammatory and tumor origin. But even more common are diseases associated with its individual sections, such as tonsillitis (tonsils) or sinusitis.
