After going through this study unit you will be able to:
- Locate the pharynx.
- Name the three divisions of the pharynx.
- Identify and describe the main landmarks of the pharyngeal mucosa.
The pharynx, commonly known as the throat, is a muscular tube extending from the nasal and oral cavities until the larynx and the esophagus. Basically, it is a place of passage for air, food, and liquids. Based on its anterior relations, the pharynx is divided into three mains sections: the nasopharynx, posterior to the nasal cavity; the oropharynx, posterior to the oral cavity; and the laryngopharynx posterior to the larynx. The pharyngeal wall is formed essentially by muscles and fascia and is covered internally by mucosa. The pharyngeal mucosa shows different landmarks that will be reviewed in this study unit.
