*Opening of the [[Larynx - Anatomy & Physiology|larynx]] is on the floor of the pharynx
+
The opening of the [[Larynx - Anatomy & Physiology|larynx]] is on the floor of the pharynx. Caudal and dorsal to the laryngeal opening is the opening into the [[Oesophagus - Anatomy & Physiology|oesophagus]]. In the dorsal region of the [[Nasopharynx - Anatomy & Physiology|nasopharynx]] there are paired openings into the auditory (eustacian) tubes. The lining of the middle ear cavity and auditory tube is continuous with that of the [[Nasopharynx - Anatomy & Physiology|nasopharynx]]. It is located between the base of the skull and the first two cervical vertebrae dorsally and the [[Larynx - Anatomy & Physiology|larynx]] ventrally. The [[Skull and Facial Muscles - Anatomy & Physiology#Mandible (mandibula)|mandible]], pterygoid muscles and [[Hyoid Apparatus - Anatomy & Physiology|hyoid apparatus]] are located laterally. Laterally, two pairs of '''palatopharyngeal arches''' are present from the [[Soft Palate|soft palate]] to the [[Oesophagus - Anatomy & Physiology|oesophagus]].

The walls of the pharynx contain striated muscle. During [[Deglutition|swallowing]], the [[Soft Palate|soft palate]] is raised which divides the pharynx into dorsal and ventral sections.

The [[Larynx - Anatomy & Physiology#Laryngeal Pharynx|laryngeal pharynx]] is separated from the [[Oropharynx - Anatomy & Physiology|oropharynx]] by the [[Epiglottis|epiglottis]]. [[Tonsils - Anatomy & Physiology|Tonsils]] are present on the lateral walls of the [[Oropharynx - Anatomy & Physiology|oropharynx]] and are covered by flaps of mucosa.
