Your Tongue Flashcards
apex
tip of tongue
blade
just behind the apex
frenulum
flap of tissue beneath apex attached to floor of mouth
papillae
taste buds are interspersed throughout
median fibrous septum
divides tongue into right and left halves
origin for some tongue muscles
what is a muscular hydrostat?
a muscular organ that lacks skeleton, bone, or cartilage
provides its own support through muscular contraction
can move in various ways
superior longitudinal origin (i)
the hyoid bone and the median fibrous septum
superior longitudinal insert (i)
lateral margins of the tongue and region of the apex
superior longitudinal action (i)
assists in retraction and elevates the tip of the tongue
inferior longitudinal origin(i)
root of the tongue and hyoid bone
inferior longitudinal insert(i)
apex of the tongue
inferior longitudinal action(i)
pulls tip of the tongue downward
assists in retraction
transverse origin(i)
median fibrous septum
transverse insert(i)
lamina propria on the sides of the tongue
transverse action(i)
narrows and elongates the tongue
vertical origin(i)
mucous membrane of dorsum of tongue
vertical insert(i)
inferior surface of the tongue
vertical action(i)
flattens the tongue
genioglossus
makes up the bulk of the tongue
genioglossus origin
deep mandibular surface at symphisis
genioglossus insertion
tip and all along the dorsum of the tongue and hyoid bone
genioglossus action
anterior fibers retract tongue, posterior fibers protrude tongue together
**look at slides
styloglossus origin
styloid process of the temporal bone
styloglossus insert
inferior sides of the tongue
styloglossus action
pulls tongue up and back
hyoglossus origin
length of the greater cornu and lateral body of hyoid
hyoglossus insert
sides of the tongue between the styloglossus and inferior longitudinal mms
hyoglossus action
pulls sides of tongue down
palatoglossus origin
velum and extends inferiors and anteriorly through the anterior faucial pillars
palatoglossus insert
posterior and lateral margins of tongue
palatoglossus action
to lower velum or to decrease distance between left and right faucial pillars
