Pharynx Flashcards
inflammation of the adenoids
adenoiditis
inflammation of a lymph node
adenitis/lymphadenitis
swelling of lymph node
lymphadenopathy
pus formation
suppurate
difficulty swallowing
dysphagia
painful swallowing
odynophagia
breathing restriction resulting in waking up repeatedly
sleep apnea
sphenoid bone to soft palate boundary
nasopharynx
soft palate to epiglottis boundary
oropharynx
epiglottis to cricoid cartilage boundary
laryngopharynx
posterior sensory innervation to nasopharynx
CN IX
anterior/lateral sensory innervation to nasopharynx
CN V2 (maxillary)
sensory innervation to oropharynx
CN IX
sensory innervation to laryngopharynx
CN X
upper portion of laryngopharynx and larynx sensory innervation (branch of vagus)
internal laryngeal n.
lower portion of laryngopharynx and larynx sensory innervation (branch of vagus)
inferior laryngeal n.
motor to muscles of larynx
inferior laryngeal n.
innervation to outer circular muscles of pharynx
CN X (vagus)
3 main constrictor muscles of pharynx
superior
middle
inferior
2 portions of the inferior constrictor muscle
thryopharyngeaus (oblique)
cricopharyngeaus (horizontal)
outer circular muscles of pharynx do what to allow food to go to esophagus
constrict and relax
innervation to most inner longitudinal muscles of pharynx
CN X (vagus)
the only inner longitudinal muscle NOT innervated by CN X
stylopharyngeus
what innervates stylopharyngeus
CN IX
what two muscles attach to soft palate
salpingopharyngeus
palatopharyngeus
muscles that elevate the pharynx during swallowing
inner longitudinal muscles
what inner longitudinal muscle also aids in inspiration and increases diameter of airway
stylopharyngeus
