Parts of the pharynx

• Superior pharynx: Also nasofaringe or rinofaringe is called when starting of the later part of nasal cavity. The ceiling of the pharynx located in nasofaringe is called cavum, where one is the faríngeas tonsils or adenoides, that when they grow in the children call vegetations. Nasofaringe is limited ahead by the coAnas of the nasal graves and by down by the veil of to paladar. To both sides it presents/displays the orifice that puts in contact ear means with the sidewall of the pharynx through Tube of Eustaquio. Detras of this orifice is receso faringeo call fosita of Rosenmüller. In the later wall of rinofaringe the relief of the previous arc of the atlas or first cervical vertebra is appraised.
• Average pharynx: Also orofaringe is called, because ahead it is opened to the mouth or oral cavity through itsmo of fauces. By above it is limited by the veil of paladar and down by epiglotis. In orofaringe they are tonsils palatal or anginas, between the palatal pillars previous or glosopalatino and later faringopalatino.
• Inferior pharynx: Also hypopharynx or laringofaringe is called. It includes/understands the structures that surround below epiglotis, like the pear-shaped sines and the retrocricoideo channel, until the limit with esophagus. In the middle of the pear-shaped sines or faringolaríngeos channels is the entrance of the larynx delimited by plieques aritenoepiglóticos.
