Gross anatomy boundaries anteriorly. It communicates with the nasopharynx superiorly and the laryngopharynx inferiorly.

The oropharynx is the region posterior to the oral cavity that includes the posterior one third of the tongue tongue base the palatine tonsils the soft palate and the oropharyngeal mucosa and constrictor muscles. The oropharynx forms part of the pharynx being the continuation of the oral cavity and nasopharynx superiorly and the larynx and hypopharynx inferiorly. The oropharynx is located between the soft palate superiorly and the hyoid bone inferiorly.

The oropharynx is innervated by the glossopharyngeal nerve. The posterior pharyngeal wall is at the level of the second and third cervical vertebrae. The superior wall consists of the inferior surface of the soft palate and the uvula.

The anterior wall consists of the base of the tongue and the epiglottic vallecula. It is divided by the glossopalatine arch from the laryngeal pharynx. The lateral wall is made up of the tonsil tonsillar fossa and tonsillar faucial pillars.

It can be subdivided into the palatine faucial arch and oropharynx proper. Inserts posteriorly into to the pharyngeal tubercle of the occiput and the median pharyngeal raphe. The lamina propria contains aggregates of lymphoid tissue called tonsils in several parts of the oropharynx.

The oropharynx has a stratified squamous epithelium. It is continuous with the oral cavity anteriorly and communicates with the nasopharynx above and the supraglottic larynx and hypopharynx below. Originates from the pterygomandibular ligament alveolar process of mandible and medial pterygoid plate and pterygoid hamulus of the sphenoid bone.

The oropharynx is behind the oral cavity below the soft palate and above the epiglottis.
