deep neck Flashcards
prevertebral mm
within the prevertbral fascia
inn of the prevert mm
cervical nerves
cervical ganglion
sup, mid and inf
where pregang sympathetics go to synapses with postganglionic cells before they project to head area
majority of lymphatic drainage to?
thoracic duct
R lymphatic duct drains R head and arm
vocal cord inn
R and L recurrent laryngeal nn’s
connection of carotid sheath
alar fascia
only complete cartilage ring of the airway?
cricoid. others are u shaped
what nerve gives off the L and r recurrent laryngeal nn?
vagus
cricothyroid
mm used for fine tuning vocalization
strap mm
sternothyroid
sternohyoid
thryohyoid
omohyoid
lymph drainage pattern
towards the int jugular
cartrilage sup to the posterior aspect of the cricoid cartilage
arytenoid
true and false vocal cords name and location
true: vocal folds/ligament, located inferior
false: vestibular fold/ligament, located superior
space between the true and false vocal cords
ventricle
lateral cricothyroid ligament, target for?
attached to true vocal cords and thyroid
target for emergency trachectomy
vocal cord positioning
attached towards the front and open towards the back
forced respiration: will open wider
photonation: will tighten/move togther
whispering: posterior aspect with arytenoid cartilages will open as the cords come together
inn of the cricothyroid
external laryngeal nn from CN X
action of the cricothyroid
stretches and tenses vocal ligament, adjust tilt and geometry of the cords
thryoarytenoid inn
inf laryngeal nn (part of the reccurent), CN X
thryoarytenoid action
relax vocal ligament
posterior cricoarytenoid action
opens the vocal fold (abducts)
posterior cricoarytenoid inn
inf laryngeal nn (terminal branch of recurrent), CN X
lateral cricoarytenoid inn
inf laryngeal nn (terminal branch of recurrent), CN X
lateral cricoarytenoid action
adducts vocal folds
transverse and oblique arytenoids inn
inf laryngeal nn (terminal branch of recurrent), CN X
transverse and oblique arytenoids action
adduct arytenoid cartilages
vocalis inn
inf laryngeal nn (terminal branch of recurrent), CN X
vocalis action
within the ligament, relax posterior ligament while maintaining anterior tension
L recurrent laryngeal nn hook around?
aortic arch
R recurrent laryngeal nn wraps around?
subclavian Aa
what nn can easily be damaged in neck surgery, result
recurrent laryngeal nn, can lead to loss of inn of the small laryngeal mm
swallowing action effect on epiglottis
will cause entire larynx to rise up and allow epiglottis to cover opening and prevent airway obstruction/ promote food down esphogus
piriform recess
spaces lateral to the vocal cords
palatoglossal/pharygeal arches
possess mm of the same names
between them is the palatine tonsil
nn of the jugular foramen
CN 9,10,11
muscles of the pharynx
sup, mid, and inf constrictors
stylopharyngeus
palatopharyngeus
salpinopharyngeus
inn of the pharyngeal mm
All inn by CN X, except the stylopharyngeus=CN IX
lymph drainage pattern
in/down towards the internal jugular
thryoglossal duct cyst
due to improper migration of thyroid tissue from the foramen cecum
