The pharynx is part of both the [[Cardiorespiratory System Overview - Anatomy & Physiology|respiratory]] and [[Alimentary System Overview - Anatomy & Physiology|digestive]] system. Both systems have entrances to the pharynx but they are separated from each other by the [[Soft Palate|soft palate]].

During exercise or during respiratory distress, the mouth can be used as an additional opening of the respiratory system and then the [[Oropharynx - Anatomy & Physiology|oropharynx]] also becomes an air-way.

==Innervation==

==Innervation==

The nervous supply comes from the pharyngeal branch of the vagus nerve ([[Cranial Nerves - Anatomy & Physiology|CN X]]) and from the cranial root of the accessory nerve ([[Cranial Nerves - Anatomy & Physiology|CN XI]]). The stylopharyngeous muscle is innervated by the accessory nerve ([[Cranial Nerves - Anatomy & Physiology|CN XI]]). The glossopharyngeal nerve ([[Cranial Nerves - Anatomy & Physiology|CN IX]]) supplies taste to the pharynx.

'''Fibroelastic aponeurosis''' supports the mucosa. The nasopharynx has pseudostratified columnar epithelium. The [[Oropharynx - Anatomy & Physiology|oropharynx]] and the [[Larynx - Anatomy & Physiology#Laryngeal Pharynx|laryngeal pharynx]] have stratified squamous epithelium. The oropharynx and the laryngeal pharynx also have [[Salivary Glands - Anatomy & Physiology|salivary glands]] present.
