what does the hard palate do? - Answer melts into the maxillary bone that holds top
teeth, whole thing is called the maxilla
what do the mucous and epithelium do in the nose? - Answer warming and humidifying
the air that you breathe in, responding to environment and air temperatures
-catches dust and things you might be allergic to or irritated by
what are the surface features of the outer nose important for? - Answer acoustically and
aerodynamically in order to produce speech
what do the 6 muscles of the pharynx make up? - Answer the tube of the pharynx
what are the 6 muscles of the pharynx involved in? - Answer vocal tract tuning
what does lumen mean? - Answer inside of the tube
what is the source of voice? - Answer larynx
what is the filter of voice? - Answer space above the VF that shape sound into sounding
like you
, how many of the 6 muscles help narrow the pharynx? - Answer 5
how many of the 6 muscles help widen the pharynx? - Answer 1
what muscle of the pharynx helps widen the pharynx? - Answer stylopharyngeus
what muscles of the pharynx helps narrow the pharynx? - Answer superior, middle,
inferior constrictor, salpingopharyngeus, palatopharyngeus
what is the muscle action of the superior constrictor? - Answer constrict the upper
portion of the pharyngeal lumen as a sphincter
-forward movement of the posterior pharyngeal wall
-lateral wall moves medially
where does the middle constrictor lie? - Answer inferior to the superior constrictor
what is the middle constrictor? - Answer fan-shaped structure located at the midportion
of the pharyngeal tube
what does the middle constrictor act as? - Answer sphincter when contracted
where does the inferior constrictor lie below? - Answer the median pharyngeal
constrictor
what is special about the inferior constrictor? - Answer most powerful of the 3
constrictor muscles of the pharynx
-this is because the upper esopharyngeal sphincter is crocpharygeal (important
transition point from pharynx to esophagus-trying to keep reflux from coming up into
throat)
what is the important movement about the cricopharngeus? - Answer when engaged,
the muscle draws the lower portion of the pharynx forward and pulls the lateral walls of
the lower pharynx forward and inward
***squeezing in***
what is the salpingopharyngeus muscle? - Answer narrow muscle that arises from near
the lower border of the eustachian tube
what is the muscle action of the salpingopharyngeus? - Answer pulls the lateral wall of
the pharynx up and inward
what does the muscle action of the salpingopharyngeus do? - Answer decreases the
width of the pharynx
-makes lumen smaller
-narrowing pharyngeal tube as well
