TONGUE MUSCLES
this muscle is primarily responsible for elevating tongue tip
superior longitudinal
TONGUE MUSCLES
This tongue muscle is primarily responsible for lowering tongue tip
Superior longitudinal
TONGUE MUSCLES
These tongue muscles are responsible for moving the tip of the tongue from side to side
Superior and inferior longitudinal
TONGUE MUSCLES
In order to make an [l], the lateral margins of the tongue have to relax, which involves protruding the tongue with the ___ and pulling the sides towards the middle with the ____
post. genioglossus; transverse intrinsic
TONGUE MUSCLES
tongue tip motion is dictated by these two
superior and inferior longitudinal
TONGUE MUSCLES
Tongue narrowing is determined by this muscle
transverse intrinsic
TONGUE MUSCLES
In order to do any type of tongue grooving, the dorsum needs to be lowered, which the ___ ___ muscles do, and the whole tongue body needs to be lowered, which the ___ does
vertical intrinsic; genioglossus
TONGUE MUSCLES
These muscles are in charge of lowering the dorsum
vert intrinsic
TONGUE MUSCLES
This muscle is in charge of moving the tongue body
genioglossus
TONGUE MUSCLES
In order to get a broad central groove, the tongue also needs the __ ___ to lift the tongue margins
superior longitudinal
TONGUE MUSCLES
In order to protrude the tongue, the ___ has to advance it, the __ __ have to narrow it, and the __ and ___ ___ muscles have to balance and point it
genioglossus; vertical muscles; superior and inferior longitudinal
TONGUE MUSCLES
In order to retract the tongue, the ___ needs to retract the body, the __ and __ __ need to shorted the tongue, and the ___ needs to move the tongue into pharynx
genioglossus; superior and inferior longitudinal; styloglossus
TONGUE MUSCLES
In order to lift the back of the tongue, the ___ lifts the sides and the ___ ___ bunches
palatoglossus; transverse intrinsic
TONGUE MUSCLES
Depressing the tongue always requires the ___, and sometimes the __ and __ if the hyoid is held in place by the infrahyoids
genioglossus; hyoglossus; chondroglossus
These three muscles are responsible for elevating the upper lip
1) levator labii superioris
2) zygomatic minor
3) levator labii superiori alaeque nasi
This muscle is responsible for closing both the lips
orbicularis oris
This muscle closes the lips by depressing the corners of mouth and compressing the upper lip
depressor anguli oris
this muscle depresses the lower lip
depressor labii inferioris
both of these retract the mouth; the second can also lift the corner
1) risorius
2) zygomatic major
this muscle’s main job is to move food to the pharynx and constrict the oropharynx
buccinator
this chin muscle can wrinkle the chin and pull lower lip out
mentalis
These four muscles can lower the jaw
1) platysma
2) digastricus (ant and sup together)
3) mylohyoid
4) geniohyoid
These three muscles are responsible for lifting the jaw
1) masseter
2) temporalis
3) medial pterygoid
The __ __ juts the jaw out, and the ___ draws it back in
External Lateral pterygoid; temporalis
This muscle elevates and retracts SP
Levator veli palatini
This muscle shortens the SP
musculus uvulae
this muscle dilates the eustacian tube
Tensor veli palatini
these two muscles can lower the SP
1) palatoglossus
2) palatopharyngeus
These 5 muscles can narrow or constrict the pharynx
1) palatopharyngeus
2-5) pharyngeal constrictors - superior, middle and inferior cricopharyngeal and thyropharyngeus
This muscle elevates the lateral pharyngeal wall
Salpingopharyn-
geus
