pharynx Flashcards
general pharynx
musculofacial tube for respiration and GI
extend from base of skull to CV6 where its continuous w/esophagus
connects oral and nasal cavities to larynx for passage of air to and from lungs
connects oral cavity to esophagus for passage of food/liquids to stomach
divisions of pharynx
nasopharynx- post to nasal cavities
oropharynx- post to oral cavity
laryngopharynx- post to larynx
pharynx communicates with
nasal cavities(2) via choanae tympanic cavities(2) via auditory tube oral cavity larynx esophagus
nasopharynx
pharyngeal recess- locates on post sup wall of nasopharynx
pharyngeal tonsi- locates w/in recess
adenoids
enlarges, inflamed pharyngeal tonsils
can obstruct nasopharynx making breathing difficult
infection can also spread to tubal tonsils, blocking auditory tube and impairing hearing.
infection can also spread to middle ear
torus tubarius
mucosal prominence formed by cartilage of auditory
tube
pharyngeal ostium below torus tubarius represents opening of auditory tube
tubal tonsils
lymphoid tissue
located near opening of auditory tube
salpingopharyngeal fold
fold of mucosa overlying salpingopharyngeus m
salpingopharyngeal m
cartilage of auditory tube
thyroid cartilage
vagus
assists other pharyngeal mm during swallowing
levator pad
located below torus tubarius
fold of mucosa overlying levato veli palatini m
oropharynx
portion of pharynx post to oral cavity
fauces
passageway from mouth to oropharynx
faucial pillars
palatoglossal and palatopharyngeal folds
laryngeal inlet
part of laryngopharynx
anterior communication with larynx
palatoglossus m
soft palate
tongue
vagus
pulls tongue and soft palate together during swallowing
