Crunch time Flashcards
Which 3 muscles elevate the larynx during swallowing?
Stylopharygneus
Salpingopharyngeus
Palatopharyngeus
True or fale? Muscles connecting the hyoid or larynx to a superior structure generally elevate them.
True
What is another term for adams apple?
Laryngeal prominence
What serves as an anterior attachment for vocal folds?
Thyroid cartilage
What direction does the epiglottis move to close the larynx?
Down and Back
Which laryngeal muscle is responsible for bringing the epiglottis down and back during swallowing while pivoting arytenoids forward?
Aryepiglottis muscle
Both sensory and motor innervation of the larynx is supplied by which cranial nerve?
CNX
What is the function of the aryepiglottic folds?
They help to channel the bolus around the airway until the swallow begins.
What is the primary muscle of the UES?
cricopharyngeus
Motor and sensory innervation to the UES is provided by what CN
Pharyngeal Plexus
Why is the UES tonically active (sustained contraction of a muscle) during non-swallowing periods?
To prevent gastric contents from entering the throat
To prevent air from entering the esophagus and stomach
What does the UES do after the swallow?
Closes
The duration of UES opening remains the same with varying bolus size true or false
False, changes with bolus size
The cricopharygneus is part of which muscle?
inferior pharyngeal constrictor
What is the brainstem responsible for?
Swallow, Sleep, Breathing, Heartrate
What is a plexus
A branching network of vessels or nerves
What are the pharyngeal constrictors innervated by?
Pharyngeal plexus
Which nerve is responsible for sensory information in the larynx?
CNX
Which CN Innervates all muscles of the jaw except the geniohyoid
Trigeminal
Innervates all intrinsic muscles of the larynx
Vagus
Innervates all intrinsic pharyngeal and palatal muscles except for the tensor veli palatini (CN V) and the stylopharyngeus (CN IX)
Pharyngeal Plexus
Innervates all muscles of the tongue except the palatoglossal
hypoglossal
These two, paired bones of the skull comprise the hard palate:
Palatine and maxillae
What role do rugae play?
positioning the bolus
