Flashcards in layrnx anatomy Deck (21):
at what vertebrae level is the larynx?
what happens at C6
larynx becomes trachea
where do the vocal cords attach?
between thyroid cartilage and vocal processes of arytenoid cartilages
space between tongue and epiglottis
mucosa of larynx?
mainly resp epithelium except vocal cords( stratatfied squamous epithelium)
false vocal cords
superior (vestibular folds)
true vocal cords
inferior (vocal folds)
mucosa in larynx is supplied by?
specifically what nerve supplies the superior vocal fold?
superiopr laryngeal branches of vagus
specifically what nerve supplies the inferior vocal fold?
recurrent laryngeal branch of vagus
what nerve gives both sensory and motor to larynx?
intrinsic muscles of larynx are supplied by?
which muscles tense the cartilages?
cricothyroid muscles (between thyroid and cricoid)
what muscles relax the cartilages?
thyro-arytenoid (pull arytenoid to thyroid)
which muscles adduct the cartilages?
rotate the arytenoids so vocal proccesses get closer together
which muscles abduct?
posterior crico-arytenoid muscles
widen rimma glottidis
which muscles contract during whispering?
which muscles contract in forced respiration?
posterior crico arytenoids
how to clinically test vagus?
ask them to swallow some water
how are oral sounds made?
soft palate tenses and moves up and directs air through mouth- most vowels and consonants are made
