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 pharynx makes up the part of the throat situated immediately behind the nasal cavity, behind the mouth and above the esophagus and larynx. The human pharynx is conventionally divided into three sections: the nasopharynx, the oropharynx and the laryngopharynx. It is also important in vocalization. In humans there are two sets of pharyngeal muscles that form the pharynx, determining the shape of its lumen.
