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. The pharynx extends from the base of the skull down to the inferior border of the cricoid cartilage (around the C6 vertebral level), where it becomes continuous with the esophagus.
1 For the convenience of description, the pharynx is divided into three parts: (1) the nasopharynx, posterior to the nose and superior to the soft palate; (2) the oropharynx, posterior to the mouth; and (3) the laryngopharynx, posterior to the larynx. 2  The pharynx is about 15 cm long. The pharynx is the continuation of the digestive system from the oral cavity. 2  It is a funnel-shaped fibromuscular tube that is the common route for both food and air. 3  The pharynx is located posterior to the nasal and oral cavities, and the larynx.
