Pharynx. The Pharynx is the main resonating chamber for the voice. The term Throat generally refers to the Pharynx. It is located behind the Mouth and Nasal cavity and above the Esophagus. It is part of both the Respiratory and Digestive Systems, acting as a passage for both air and food during normal daily behavior.The Pharynx is made up of three parts:t extends from the Larynx itself up to the Oropharynx behind the mouth. The Laryngopharynx is actually behind the Larynx and is defined by the form of the Epiglottis. It is directly above the Esophagus and serves as the junction of the Pharynx and Esophagus.
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.ach lateral wall of the nasopharynx has the pharyngeal opening of the auditory tube, located about 1 to 1.5 cm (1) inferior to the roof of the pharynx, (2) anterior to the posterior wall of the pharynx, (3) superior to the level of the palate, and (4) posterior to the inferior nasal concha and the nasal septum (fig.
